Keeping you up to date with the latest CorkSport Mazdaspeed news!
Category: CX-7
The CX7 was Mazda’s crossover released in 2007 which offered the same turbo engine the Mazdaspeed 3 and Mazdaspeed 6 came equipped with. Complete sleepers on the street.
Based on popular demand, we have developed a filter sock that will help fight dust and water spray from entering the engine. The CorkSport Mazda Air Filter Cover mod can help maintain the flow efficiency of your main filter and extend its service life.
Quality Materials
The Air Filter Cover is made from a polyamide fabric mesh and allows for good airflow while adding a layer of protection for your air filter and engine. The cover protects against dust, large debris, and light water spray from entering the filter media.
The small air filter sock works on 3.0, 3.5, & 4.0 marked air filters only
The large air filter sock works on the 4.5 marked air filter only
You can check your CorkSport air filter here:
If you don’t have a CorkSport specific intake, there is still a good chance your Mazda can enjoy the benefits of our air filter sock. Follow the diagram below to see if your air filter size matches:

Replace every seal in your HPFP with a brand new, E85 safe O-ring/X-ring made to exact OEM specifications. The perfect reliability upgrade to install with your CS HPFP internals, we even include new hardware and a security Torx bit to help the install go smooth. Read on for more details and be sure to give us a call if you have any questions!
Mazdaspeed E85 Safe HPFP O-Ring Rebuild Kit

The potential for HPFP failure
While the HPFP internal upgrade is a must-have mod for any Speed, the rest of the HPFP is commonly ignored. As the cars get older and ethanol blends are used more often, the factory O-rings can begin to break down, causing fuel dilution in your oil, and the potential for HPFP failure. The CS HPFP rebuild kit replaces all your seals so you can be confident that your HPFP is performing exactly as intended.

Was the HPFP system designed with ethanol in mind?
With the MS3 and MS6 coming out right around the time ethanol mixes in gasoline were becoming more common, it’s hard to say if the HPFP system was ever designed with ethanol in mind. We spent months researching and testing on a car and in isolated conditions to find the best O-ring material for gasoline and ethanol blends. Each seal in the CS HPFP rebuild kit uses this material so your Speed will operate properly no matter if you’re using the standard pump gas E10 mix, and E30 mix, or even straight E85!
CorkSport
To ensure the correct size for all seals, we were lucky enough to come across a zero mile DISI MZR engine. The HPFP was disassembled and all seals were carefully measured to ensure each O-ring exactly matches the OEM specification. We even had tooling made to produce a custom X-ring that matches the exact specification of the OEM X-ring. This is vital as the X-ring fits on your HPFP piston and needs a precise fit to ensure an OEM quality seal between the fuel chamber and your cam follower.

Lastly, we include hardware to replace the annoying Torx screws that are used in the OEM HPFP assembly. The small security Torx can be notoriously difficult to remove, so we even include a bit to help with removal. As with all CS products, the HPFP rebuild kit comes with full-color installation instructions to guide you through the rebuild and ensure you know where each and every component goes.
CorkSport Built Long Blocks for the 2006-2013 DISI MZR
You’ve probably seen the stellar videos posted on our news feed or heard the rumors about CorkSport building stout long blocks for our employee’s Mazdaspeeds and the company R&D Mazdapeed. Today, we are ready to let the “cat out of the bag.”
CorkSport is building long blocks for your Mazdaspeed and here’s why it will interest you:
We have complete long-blocks ready for installation with blueprint certificates. These long-blocks are in-stock and are ready to ship. If you’d rather send us your motor, we guarantee one month or less turnaround.
Let’s check it out:
Every engine is meticulously inspected and measured to extremely precise tolerances per our ASE certified master technicians. Critical surfaces are measured to the 0.0005” for the pistons, bearings, and camshafts to create a tight, powerful, and reliable engine setup that you can depend on. To support this, every engine comes with a blueprint certificate to confirm all critical tolerances in your engine.
Better yet, this precision doesn’t come with at the cost of a 3-6 month wait. We intend to have these motors in stock. Even if you send us yours for a rebuild, we guarantee we will have your engine ready to ship faster than the industry standard!
No bull pricing means you get exactly what we list out here.
At no point will you get a call from CorkSport stating extra work or cost is needed to get your engine complete and ready for you. We’ve all been through this; starting a build with one budget and ending with a different, much larger, budget. We hate it and we won’t let it happen to you.
Other than the block and cylinder head themselves; all the parts going into your build are brand new, not reconditioned or re-used. This includes genuine OEM Mazda components; Manley connecting rods and Mahle pistons, ARP fasteners (specifications depend on Dankai Build), along with CorkSport Camshafts, Injector Seals, and other supporting parts.
Finally, what good is all this if your engine can’t get back to you safe and secure?
We want your new built block to arrive for delivery without issue, that’s why we use heavy duty sealed plastic crates that are designed to ship engines. This provides ample mounting and restraining of the engine block in the upright position for easy access for you. Along with that your engine ships free of charge within the lower 48 states. Just return your good engine core in the provided crate and get the core charges refunded.
This sounds pretty great, right? If you’re thinking about a built engine for your Mazdaspeed, then I invite you to check on the CorkSport Dankai Engine Builds to see which version fits your goals and desires.

CorkSport Built Engine December 11th, 2018CorkSport
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.
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 Mazdaspeed 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 Parts.
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 Mazdaspeed6 a few weeks ago, doing a ton of maintenance before mods. This er 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!
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.
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. (Check out all the updates for Barett’s Mazdaspeed 3)
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 Mazdaspeed3 Big Brake Kit.
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
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
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.
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.
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, Big Brake Kit (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.
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.
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.
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)
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.

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.
Looking to add some Extra Excitement to your Mazdaspeed?
What if we told you could add extra engine protection at the same time? Introducing the new CorkSport Balance Shaft Delete Kit for 2007-2013 Mazdaspeed 3, 2006-2007 Mazdaspeed 6, and 2007-2012 Mazda CX-7. It contains all the parts you need to safely remove the OE balance shaft from your MZR DISI engine and give it the extra rev-happiness that it needs.
The OE balance shaft is an 18-pound lump that lives in your oil pan to help balance out the natural vibration and harshness that are inherently present with an inline four-cylinder engine. It does this by connecting to a large gear on your crankshaft and using rotating mass to help cancel out the vibrations from the engine. By removing the balance shaft, your engine has less weight to turn and thus, can change RPM more rapidly. If this sounds familiar, it’s because lightweight flywheels do the same thing; remove some of the rotating mass of the engine to gain a faster revving engine and even a few bonus horsepower.
The OE balance shaft needs an oil supply to ensure that it stays well lubricated and does not lock up. The CorkSport BSD Kit uses a stainless steel plug and O-ring to seal this oil passage. The O-ring is not enough to seal and keep the plug in place, however, it is locked down by a securing plate which gets attached using one of the OE balance shaft mounting holes. We chose stainless for its strength over aluminum. By doing so allowed us to create a lower profile plug with a thicker O-ring for better sealing. We were also very careful to choose an O-ring that is safe for all types of oil and safe up to 400°F.
But you may be asking where does the engine protection come from?
Since the OE balance shaft lives in the oil pan, it takes up some volume that could otherwise be used for oil capacity. This means roughly a quart of extra oil can be used once the BSD kit is installed. Also, the CorkSport Balance Shaft Delete Kit comes with an oil pan baffle to help control your oil’s movement during aggressive driving.
While rapidly changing direction or during a long sweeper at high speed, the oil in your oil pan can move around a surprising amount. If the wrong set of circumstances happen, your engine can be starved of oil, which can easily damage vital engine components. The CorkSport Oil Baffle controls your oil’s movement, ensuring that your engine will have a good supply of oil no matter the driving situation.
We again choose stainless over aluminum for the oil baffle, so that it is rigid enough to control your oil and prevent any vibrations or rattles while your engine is running. The oil baffle is made from two laser cut pieces that are then attached using stainless steel rivets to eliminate any risk of corrosion or improper hole alignment.
Note: the CS BSD Kit comes fully assembled and ready for installation.
Since the CorkSport BSD Kit removes a stock component designed to make the car more comfortable, it will naturally have an increase in noise and vibration coming from the engine compartment. As such, we cannot in good conscience recommend this mod to everyone. That does not mean it is unbearable though, Barett at CorkSport still daily drives his fully mounted Mazdaspeed3 with a CS BSD Kit installed.
If you are looking for the next mod to get some more excitement from your Mazdaspeed, look no further than the CorkSport Balance Shaft Delete Kit. After all, how many mods come with some extra engine health as well?
