The CorkSport EGR Delete Kit is Here!

If you’re looking to help your racing engine stay healthy and clean, read on as we introduce the CorkSport EGR Delete Kit for Mazdaspeed 3, 6, and Mazda CX-7 Turbo.

An exhaust gas recirculation (EGR) system is a very common control system that recirculates some exhaust gases back to the intake manifold to help reduce NOx emissions. A properly functioning system has a few other minor benefits however, on the DISI MZR the EGR system primarily gets clogged,  and/or gums up your intake valves, reducing engine health and performance (for more info, check out our blogs on EGR Cleaning and Intake Valve Cleaning).

The CorkSport EGR Delete Kit removes the two primary components in the EGR system: the EGR valve and the EGR tube. This means no more carbon and soot going into your intake valves, and when coupled with a quality Oil Catch Can, much less frequent valve cleaning.

Each CS EGR delete kit comes with everything you need for a good looking, easy install. The EGR valve is replaced with a 3/8” thick, billet aluminum block off plate. The plates are precision machined to closely match the OEM EGR valve flange to keep your install clean. Proper length bolts are supplied with the CS EGR Delete Kit to ensure you won’t damage your OEM or CS High Pressure Fuel Line.

The EGR tube delete consists of two components: a laser cut 18 gauge T304 stainless steel block off plate and a T304 stainless plug. The plate can be used underneath the tube itself for a stealth install or for an even cleaner engine bay, go for the full tube delete and use the plug to block the hole in your OEM intake manifold.

While not a typical performance mod, the EGR delete is a great addition to aid in a racing build’s future mods. To start, the EGR valve block off plate is tapped for the included 1/8”-27 NPT barb fitting. This works great for the OEM turbo’s rubber coolant line, but should you upgrade to a non-water cooled turbo or a stainless coolant line, 1/8” NPT is a very common size that should be able to accommodate almost any type of fitting.

The CorkSport EGR Delete Kit also provides some much needed room around the turbo charger. With the bulky OEM EGR valve removed turbo swaps are easier, plus, certain turbo setups will literally not fit without an EGR delete. Finally, should you decide down the road to upgrade your Intake Manifold, an EGR delete is basically a must as nearly all aftermarket intake manifolds remove the EGR port from the IM.

The CorkSport EGR Delete Kit is a relatively easy way to gain some extra engine protection without breaking the bank. If you just cleaned your valves and want to avoid it doing it for a long time, a CS EGR Delete Kit is a must.

Safely Upgrade Your Mazdaspeed Turbo

It doesn’t take long for those building power to use up the stock K04. They are prone to fail, especially when you start shoving that extra air through it. A common question is, “My Mazdaspeed is smoking, is my turbo bad?”

First things first. There is a BIG difference between replacing a bad turbo and upgrading to a more efficient one for more power. If you want to replace it, go with OEM and just plug and play, you’re good to go, wash your hands and get on with your life. This will have your car up and running pretty quickly. However, your maximum power output will be limited and you will eventually have the same problem – the KO4 will fail.

If you are saying to yourself, “It’s time to upgrade…I NEED more power in my life!” Then this blog is for you. Below, we lay out the basics needed to successfully install a CorkSport Mazdaspeed Turbo, highlighting the required supporting modifications to keep your Mazdaspeed safe. And as an added bonus, we keep our installation instructions on each of our product pages, so you can preview how easy the install will be for your experience level.

Here it is, the list is comprised of the BARE essentials to run the 18G CorkSport turbo.

 

HPFP INTERNALS

Giving you 50% more efficiency with your fueling system, as well as, a strong base to build power for your Mazdaspeed. The CorkSport Max Flow Fuel Pump Internals are built to directly replace your stock fuel pump internals and perform with immediate improvements.

CorkSport fuel pump vs. competitors

ACCESSPORT (or VERSATUNE if you have a CX-7)

The Cobb Accessport will give you the basis for tuning, and since this is required with the CorkSport turbo – you’ll want to make sure you have this in hand and ready for when you install your turbo.

These are the basic foundation to our Mazdaspeeds, without these two items you cannot operate your Mazda after installing an upgraded turbo.  You will need your Mazdaspeed tuned, and your tuner is going to say the same thing.

That’s it, that’s all you need to run the CorkSport Mazdaspeed turbo safely. With this proper foundation, you can put yourself in a position for efficiency, or more power.

Now the question is do you want to make it go fast and harness the power that this turbo is built for? Keep reading and we’ll provide some other awesome upgrades that are the next step once you have your turbo installed and running.  Oh, and if you are looking for a proven path to make 400WHP, check out our Chasing 400 WHP Blog here!

CorkSport Upgraded 3.5” Intake

The CorkSport turbo is rated for up to 450WHP with the right set up. Unless you are going for the MOON and shooting for over 700WHP a 3.5” intake will be more than sufficient for this turbo. Giving you some extra airflow to increase your power range, and harness what your Mazdaspeed3 is capable of. Note: Will require additional tuning!

 

CorkSport Mazdaspeed Downpipe

Doesn’t matter if you go with a high flow catalyst or opt-in for one without, the choice is yours. However, if you want to utilize its flow you are going to have to upgrade to a bigger diameter. Our 80mm one does really well, plus it sounds GREAT.  Note: Will require additional tuning!

The CorkSport Cat Back Exhaust System gives your new 2016 Miata the power it needs without the annoying drone.

CorkSport Cat-Back Exhaust

It’s no secret that car engines are just big air pumps, the faster you can shove air into the engine and how fast you can expel it efficiently is what it takes to make more power. No need to run the stock 63.5mm exhaust when you can run our 80mm (like to wake up the neighbors every morning, go with our non-resonated, you can’t beat the cold start)

CorkSport Top Mount Intercooler

If your power goal is 450whp or less you can get away with just upgrading your TMIC and be on your way and they look great in your engine bay.  Note: Will require additional tuning!

If you have the 2nd gen you can really utilize that hood scoop from the factory.  Not only that but you can even see a noticeable performance gain with our larger hood scoop and a TMIC set up.

 

When it comes to your Mazdaspeed we know you want to create safe power and harness the true potential of your ride. Be sure to build upon the proper foundation and head in the right direction for your build. Our techs are available for any questions you have and are ready to assist with planning your Mazdaspeed build path! Any questions – give us a call directly – (360)260-2675, email to sales@corksport.com or leave a comment and we’ll get back to you!

Intake Valve Cleaning – A Dirty Job Made Easy

Introducing the CorkSport Intake Valve Cleaning Kit. While designed specifically for the DISI MZR engine found in the Mazdaspeed 3, 6, and Mazda CX-7 turbo. Our kit is versatile enough to be used in a variety of direct injected (DI) applications and alleviates many of the pain points associated with cleaning your intake valves. For an explanation on why DI engines need their valves cleaned, check out our blog on cleaning Mazdaspeed intake valves. Read on as the CorkSport Valve Cleaning Kit could make your next maintenance job much easier.

Despite its interesting appearance the CorkSport Valve Cleaning tool was carefully designed for ease of use. Starting at the large end, the cone shape was selected to accommodate a wide variety of vacuum hose sizes (1.50-2.5- inch OD) – it even works with the oblong-shaped hose we have in the CS shop! A clamp is included to keep the tool secure on the vacuum. Due to the slightly flexible nature of multi-layer silicone, clamping the hose creates a seal useful to get great suction from the vacuum.

To provide the best fit for both the large and small intake ports of the DISI MZR, the opposite end of the valve cleaning tool also is flared. When in use, this flare compresses slightly, making for another great seal. This keeps the cleaning chemicals, media, and any carbon deposits from getting all over you and your engine bay.

Last but not least is the small diameter offshoot on the side of the CorkSport Intake Valve Cleaning Tool. This is the port for a media blaster that helps make quick work of dirty valves. It is positioned for easy use, where one hand holds the CS valve cleaning tool while the other operates the media blaster. An abrasion resistant hose is included to fit on the end of your media blaster and travel down into your intake ports for direct blasting. Unlike doing this without the tool, you do not have to permanently modify your vacuum just to do valve maintenance.

There you have it, folks, quite possibly the weirdest looking CS product ever created but it’s quite useful!  Check out the listing for more details and to see the CorkSport Intake Valve Cleaning Tool in use.

Intakes for Mazdas

The CorkSport Cold Air Box pairs perfectly with the CorkSport Short Ram Intake.

An Intake for Every Engine

When it comes to the breathability of your Mazda, an intake is the best place to start. The benefits are immediate, the installation is quite simple and it’s genuinely the best first step to getting some power and fun out of your Mazda or Mazdaspeed.

Bringing more air into the intake chamber, the intake system allows you to increase horsepower and torque for your Mazdaspeed. Each is designed to maintain optimal flow and generate ideal performance for your Mazda, with exacting tolerances and using the latest in computer-aided manufacturing techniques to bring you the highest quality and best-performing part for your money. You can expect to gain up to 30+ HP from this simple to install intake system.

The CorkSport Cold Air Box pairs perfectly with the CorkSport Short Ram Intake.

Types of Air Intake systems

Short ram air intakes suck in large amounts of heated air within the engine to help in efficient combustion. These are short and wide pipes because it uses a shorter pipe than the cold air intake, it only has access to warm air near the engine. To make up for this, it sucks in more air than cold air intakes.

Cold air intakes are a type of ram air intake systems that work by drawing in cool air from outside and into the Mazda’s engine. This type of intake often has minimal bends and has a long duct with access to cool air. With cooler air coursing through the engine, combustion requires less heat and fuel.

Why Replace Your Mazdaspeed or Mazda Air Intake System

More often than not, car enthusiasts and expert mechanics recommend that you purchase an air intake as soon as possible. Even vehicles of the latest makes and models benefit from an aftermarket air intake system. Below are five of the reasons why an air intake system can improve your Mazda engine’s performance.

Get your 2014 Mazda 3 the cold air it needs with the CorkSport cold air box that goes perfectly with the CorkSport SRI.

Keep in mind, when an intake is paired with a cold air box, or battery box, you create a great look for your engine bay and increase your overall Mazda performance. Also, when paired with fuel pump internals, you’ll be able to increase the efficiency, power and set yourself up for future modifications as well!

Why replace your intake system?


1. Increased Acceleration
With an upgraded intake, your Mazda can experience increased horsepower. Upgraded intakes can also increase your engine’s responsiveness when speedy acceleration is required. Because there is more air available and ready for combustion with aftermarket air intakes, your engine reaches the desired speed faster compared to the stock intake that comes with your Mazda. Those who enjoy racing, autocross, or drag strips with their Mazda or who if you just like quick acceleration as soon as the traffic light turns green, an aftermarket air intake can help you enjoy your get up and go a bit more.

2. Greater Fuel Economy
Engines rely on a mixture of fuel and air to create an explosion that powers your Mazdaspeed. When there is not enough air pumping through the engine, your Mazda consumes more gas to compensate for the lack of oxygen. Stock intakes that come with your Mazda are designed to be quiet instead of fuel efficient, and as a result, they tend to use more gasoline. Pumping in more air via an upgraded intake can reduce gas consumption and translate to savings on fuel expenses. For those who are concerned about fuel efficiency…we should note here: that the enhanced sound may cause you to have a heavier foot and decrease your fuel efficiency in exchange for spirited driving.

3. More Effective Filters
The stock air intakes that come with your Mazda normally have disposable paper filters to catch debris. While these filters do their job in trapping particles that may potentially wreak havoc on your engine, the filters eventually require replacement (often a great upsell item for your local technicians). Aftermarket intakes, on the other hand, are equipped with filters that typically have to be cleaned every 20,000 to 50,000 miles (just some soapy water and let it dry completely before reinstallation). This not only saves money but it also provides a more effective filtration method that not only keeps debris out but also lets a larger qty of air inside.

4. Enhanced Sound
Those who like the aggressive sound of a roaring Mazdaspeed engine should enjoy our upgraded intakes the most. Because more air enters through the intake to the engine, it produces a sound that our Mazda enthusiasts find thrilling.

5. Better Overall Performance
With the simple installation of an upgraded intake, you can increase the overall performance of your Mazda. Whether you decide to go for the short ram or the cold air intake, you increase your Mazda’s efficiency, speed, power, and sound.

2018 CorkSport Garage Update

CorkSport's Mazda 3 guide.

CorkSport Garage

How about something a little different from the usual CS blog? I thought I would give you all a little insight into all the different Mazdas that are owned by employees. Some are daily drivers, some are full racecars, and some are…different (more on that later). So grab a cold refreshment, we’ve got quite a few cars to go through.

The Mazdaspeeds

Owner: Corey
Year/Model: 2004 Mazdaspeed Miata
Mileage: 28,800

Modifications: Full Flyin’ Miata CAI, polished stainless piping, Turbosmart recirculating bypass valve, manual boost controller, O2 signal modifier, boost gauge. Recent Mustang Dyno showed a consistent 189.9WHP.

Corey’s Comments: Purchased new to me at 17,000 miles in 2012 for my 40th birthday. The MSP Miata had been stored for 4 years-everything was original, even the tires. This Miata came from California and had never seen rain. I keep it in the garage and it’s mainly a fair weather/weekend car except during the summer. I enjoy taking a ride in the MSM with each of my kids, but love honking the horn at people and making my son wave back…like he knows them.

Owner: Luke
Year/Model: 2009 Mazdaspeed 3 GT
Mileage: 124,000

Modifications: Full bolted, built engine, CS prototype turbo, methanol injection. Too many CorkSport Par

Luke’s Comments: Car has been through stock turbo/stock block, CS turbo/stock block, CS turbo/built block, 35r/built block, and now CS prototype turbo/built block.  Fun fact: my girlfriend went faster in my car than I did when I first bought it.  Stock turbo went 12.8 @ 110mph in the  1320.

Owner: Daniel
Year/Model: 2007 Mazdaspeed 6
Mileage: 68,000

Modifications: Custom front license plate delete, CS Interior LED Kit, daily driver dirt.

Daniel’s Comments: Just bought the MS6 a few weeks ago, doing a ton of maintenance before mods. This Mazdaspeed6 started out as a dealer fleet vehicle (whatever that means). Bought it from a guy who owned it the past ~9 years. Hoping to sneak some new Mazdaspeed 6 parts into the CS catalog and feed the zoom-zoom obsession!

Owner: CorkSport (shop car)
Year/Model: 2013 Mazdaspeed 3
Mileage: 14,000

Modifications: Virtually everything in the CS catalog for MS3. Plus a few prototype parts that never made their way to the market.

Comments:  Affectionately called “Whitey”. On its 2nd built engine (we use and abuse this thing). This was one of Vincent’s first projects when he arrived at CS: rebuild Whitey’s engine. He just got done rebuilding it for the second time and is now breaking it in.

Owner: Barett
Year/Model: 2009 Mazdaspeed 3
Mileage: ~135,000

Modifications: Manley internals, L19 head studs, CS cams, bowl work & porting, all the bolt-ons, 28gph methanol injection, prototype CS turbo, 330mm BBK, other suspension bits.

Barett’s Comments: More info on the engine build here. Made ~465whp at the 2017 CS dyno day. My car hates me and is a constant work in progress.

Owner: Brett
Year/Model: 2013 Mazdaspeed
Mileage: 37,000

Modifications: Full CS bolt-ons, big turbo, meth injection, making 430whp 385ft-lbs. BC coilovers w/ custom rated Swift springs, BMSPEC front splitter, Varis rear diffuser, custom side skirt extensions, Volk TE37SL: front 18×11 rear 18×10, paint matched 240Z flares, 330mm BBK.

Brett’s Comments:  I’ve had the Mazdaspeed3 for about 4 years now. It has every CS bolt on in the catalog. Helps that I work here now. This MS3 makes ~430 WHP, and is a stock block for now; built block soon to come. I take more pictures of this car than I do anything else. 

The GEN 3’s

CorkSport's Mazda 3 guide.
Ready to mod your Mazda 3? You will be after you read this!

Owner: Jennifer
Year/Model: 2014 Mazda 3 2.5L Hatch
Mileage: 100,000

Modifications: Most of the CS catalog for GEN3: Intake, exhaust, lowering springs, adjustable struts, rear sway bar, aluminum skid tray, etc., GEN2 MS3 wheels, big CS livery.

Jennifer’s Comments: The car has been used for the majority of the Mazda3 research and design at CS. This Mazda 3 is daily driven ~80miles each day to torture test CorkSport parts, it helps that the commute to my house is that far round trip. Basically, my daily drive is a perfect example of “running up a hill both ways” for this Mazda 3.  

(Left)

Owner: Collin
Year/Model: 2016 Mazda 6
Mileage: 40,000

Modifications: CS RSB, prototype CS FSB, CS RMM, prototype CS performance header, CS license plate kit.

Collin’s Comments: Aside from the performance parts available at CS, I chose this car due to the extra ~30HP compared to most commuter cars. I still get 42MPG on my freeway commute. This is my first New Car I bought myself and I have loved learning how to modify on it. 

(Right)

Owner: Rich
Year/Model: 2014 Mazda 6 GT

Modifications: CS lowering springs/struts, CS front camber plates, CS rear camber arms, CS SRI, CS catback, CS radio control knob, CS license plate kit, 25mm wheel spacers

Rich’s Comments: I drove around the same B2300 for many years while we built CorkSport from the ground up. I finally decided to treat myself and picked this Mazda6 up in 2014. Big shift, and I’ve loved having the luxuries of this Mazda 6. 

Owner: Derrick
Year/Model: 2014 Mazda 3 2.5L Sedan

Modifications: Caged, stripped, CS SRI, straight pipe to CS axleback, bunch of custom adjustable suspension, BBK (sometimes), custom racetrack-modified bodywork.

Derrick’s Comments: This Mazda3 could not be sold as a road legal car, so I don’t drive it on the road. There are a TON of track hours on this Mazda 3 and all of it’s modifications. We basically TRY to break our test parts before we let them hit the market, which is good for me because I love to go fast.

Owner: CorkSport (shop car)
Year/Model: 2018 Mazda 3 2.5L Hatch
Mileage: 2900

Modifications: CS struts, CS lowering springs, CS camber plates, CS RMM.

Comments: Mainly stock so far, big things to come to the “CBR” (CorkSport Branded Ride). Brett, who has been dailying the CBR, somehow only is getting 23mpg. Expect more parts for facelifted GEN3’s with the CBR’s arrival.

The Others

Just because you may not have seen much about them and they don’t get their own category does not mean they’re not special. For me, some of the most interesting cars are down below.

Owner: CorkSport (shop truck)
Year/Model: 1995 Mazda B2300
Mileage: 160,000

Modifications: Sweet stickers for extra HP, tire shop wheels, custom faded paint

Comments: Vincent used to own this truck before selling it to be the “new” CS shop truck. He notes that it was involved in 3 accidents, each time the insurance company did not total the truck, leaving Vincent with more money than he spent to buy the truck. No power steering provides an arm workout for those lucky enough to drive this beast.

Owner: Derrick
Year/Model: 2016 Miata Launch Edition.
Mileage: 24,000

Modifications: Full CorkSport ND Miata catalog – CS cold air intake, CS catback exhaust, CS front and rear swaybars, CS lowering springs, CS adjustable front end links, VersaTune CS parts tune, CS short shifter – Sparco Drift wheels, Bridgestone Blizzak run flats

Derrick’s Comments: The ND is an interesting car for me as being a lifelong Mazda enthusiast I had never owned a Miata before.  When the ND was announced I had already converted the Mazda 2 into a B-Spec car so I stopped street driving it and went back to my Rx7 turbo as my daily driver so I had gotten used to driving a car with “issues” again.  When I got into the ND for the first time and drove it home it was very surreal expecting some weird sound or smelling hydrocarbons (the Rx7 is old and catless) and the car handled incredible right out of the box.  Of course that lasted all of 3 months until we have Kenton Koch behind the wheel helping us out with the suspension development.  It is one of those cars that I warn people, if you drive it you will want to buy one.

Owner: Vincent
Year/Model: 2010 Mazda RX-8 R3
Mileage: 60,000 (original engine, no issues)

Modifications: Turbo XS exhaust, K&N high flow filter, custom VersaTune tune, DBA club spec rotors, Hawk Street/Race pads, Goodridge stainless steel lines.

Vincent’s Comments: I had been wanting a 2nd gen RX-8 since high school. This thing revs out to 9400RPM and is super fun to drive. Just recently sold (hi Aaron) but too good to not include in this blog.

Owner: Derrick
Year/Model: 1993 Spec Miata
Mileage: “Lots and lots” (this car has run 25hours of Thunderhill a few times on top of all its other racing)

Modifications: Spec Miata Bilstein shock package, Eibach swaybars, illegal plunge cut cylinder head (lookup spec Miata plunge gate 2014), GLoc brakes, 949 6ul Spec Miata wheels, AIM dash & datalog system, ESR drive side drop floor, Really big radiator.

Derrick’s Comments: I took the advice of all the spec miata people and bought a built car so I didn’t have to spend 6 months building one myself.  The local car was raced for a long time in the northwest and was a front running car before it was parked for a few years.  I picked it up for ~6k with some extra spares and was immediately able to get on the track and go racing after the installation of the drop floor and new seatbelts.  The big question I have people ask me is why did you get a SM?  The real answer is the level of drivers in the class.  At any sanctioned race event weekend there are always SM and someone to race against and I have personally known several drivers go into SM a novice and come out the other side in pro racing.  To win at SM you have to have your shit together.  To be the best you need to compete against and beat the best so here I am.

Owner: Barett
Model: Mazda B2600i
Mileage: ?

Modifications: Solid axle swap with Toyota running gear, 4.88:1 axle gears, rear locker, 3 feet of articulation, 8000lb winch, high bolstered seats, 35×14.5R15 Super Swamper Bogger Tires, “lots of f*ckery fabrication.”

Barett’s Comments: This was my first real vehicle, and it taught me lots about owning a vehicle, modifying a vehicle and I have more memories with this beast than I can come up with right now. I beat the SH*T out of this truck and it’s always put away wet.

 Owner: Rich
Model: 1988 Mazda Rx- CONVERTIBLE

Modifications: Turbo engine swap, Apexi Power FC, CS Border Style body kit, CS front mount intercooler, CS turbo back exhaust, many other mods.

Rich’s Comments: The Rx-7 is kept in the garage and it’s mainly a fair weather/weekend car except during the summer. I take it out for special occasions or to just show off every once in a while. It’s a nostalgia piece for me. 

Not Pictured:

  • 2016 Mazda 3 Sedan. Derrick’s 2nd racecar. Caged, stripped, 2.0L AT converted to 2.5L MT.
  • Mazda RX-7 FC. Owned by Derrick.
  • NA Mazda Miata. Parts car for Derrick’s Spec Miata
  • Mazda 5. Derrick’s wife’s car.
  • Mazda CX7. Kelly’s daily driver.

For those keeping score, that’s 22 Mazdas in the CorkSport garage. The cars have come and gone over the years but one thing will always stay true: our cars will be fun to drive because they are Mazdas. Here’s to more Mazdas finding their way into the CS (and your) garage.

Oh and if you have any questions on the above cars, please let us know down below, we’ll be sure to pass on your question to the car’s owner.
