The Wait Is Over: The CorkSport Performance Intake Manifold Is Here

Can you believe we started this project back in 2012?

Yes, it’s been a long journey, and a few too many “two weeks”, only to find that more improvements were needed. We’ll be frank, this has been a challenging project to tackle, but we have prevailed. We have pushed past the challenges faced in manufacturing the complex design, and are proud to announce that we are ready to present you with the most complete solution for the Mazdaspeed 3 and Mazdaspeed 6 platform. Introducing the Mazdaspeed Intake Manifold!

Intake Manifold for the Mazdaspeed 3/6

The CorkSport Intake Manifold is here for those of us who want some more flow in our lives.

Our design focuses on performance without sacrificing OEM fitment or drivability. With equal flowing runners, higher flow than OE, and TMIC fitment, it truly is a complete solution to the OE intake manifold.

Fitment is huge when it comes down to large engine components like intake manifolds. While designing the CorkSport IM, we wanted to retain as many OE features and mounting locations as possible while maintaining neat and tidy packaging. By doing so, we were able to keep components such as the TMIC, OEM throttle body, MAP Sensor, and even the oil dipstick bracket in OE locations. This all means a relatively quick and easy part to install, but we made it even easier by clearing some space around hard-to-reach areas.

The CorkSport Intake Manifold may fit like OE, but that’s where the similarities end.

The CorkSport Mazdaspeed Intake Manifold is designed with performance and drive-ability in mind, with the larger plenum design and long cylinder runners. Since the intake plenum is about three times larger than OE, there is an increase in high RPM power capacity without sacrificing throttle response and drivability. By maintaining the length of the cylinder runners (vs the typical aftermarket intake manifold), we improved mid-range power while still having peak RPM capacity with the single runner design vs. an OE split runner design.

The increase in performance also comes with an increase in engine health.

By optimizing the design for equal flow between runners, the CorkSport IM eliminates the flow imbalance of the OE intake manifold. This significant imbalance causes cylinders to run excessively lean or rich, affecting engine durability and performance. Check out the graph below to see the difference. Not only does the CorkSport Intake Manifold outflow the OE design by 70CFM per runner on average but also significantly reduces the flow imbalance to 2% or less vs the OE imbalance of 21%.

This means your engine can run stronger, longer, and have a higher potential to make power.

But enough talk about numbers and flow, let’s SEE some numbers. The dyno graph below shows the difference before and after the CS IM on a Mazdaspeed3 with a CorkSport TD05H-18G turbo equipped. Not only was there an increase in power and torque across the entire RPM range, but the turbo also spooled around 100RPM faster than with the OE intake manifold.

But wait there’s more! Along with the overall design improvement over OE; there are additional design features that you need to know about.

  • Firstly, we increased the size of the throttle body opening. This allows the OE throttle body to work great but also allows for a larger throttle body to be installed without modification.
  • Next, there are added fueling ports for each runner. They are standard 1/8-27 NPT ports that can be used with methanol nozzles or other fueling options.
  • Finally, there is an extra 1/8-27 NPT port that can be used for boost controllers, gauges, or the like.

Now you may be thinking, But there aren’t any larger throttle bodies available. To that, we say, not just YET!

Along with the great features of this new Performance Intake Manifold, we are also providing nearly all of the hardware you need for installation; that is, the brass fittings that come pre-installed on the intake manifold and the additional hardware and hoses needed for auxiliary components.

Now we would like to circle back to where we started with this conversation:

We here at CorkSport pride ourselves on doing everything in our power to provide you, our customers, with the best possible products out there. We also are committed to being real with you guys as well, because we too are Mazda-lovers who get a thrill out of overcoming the toughest challenges that stand between us and the ultimate car experience.

The most challenging aspect of this project has been getting the manufacturing to an acceptable quality, and consistent among each intake manifold. We have tested the intake manifold on multiple cars in-house and with various beta testers, the results speak for themselves: this is an exceptional performance product that your Mazdaspeed will love to have.

Believe us when we say that this design is tough to manufacture,  and that process results in no two parts being exactly the same visually; but it also means that each manifold has its own unique look and character, the same way our cars do.

Track Tested CorkSport Approved 3rd Gen Mazda 3 Parts – Leading the Pack.

The last race weekend I had available before the runoffs turned out to be pretty interesting.

Locally there are very few T4 (touring 4) class cars so I often find myself running with other class cars and this weekend was no exception at Portland International Raceway. I showed up for qualifying on Friday morning with a new part to test and a suspension setup with something I had not tried.

I looked over the entry list the day before, and there read a list of cars you would expect to clobber a Mazda 3 on the track. 3 Porsche 911s, a pair of V8 mustangs, an STL Miata and more.

To make sure I had a clear track for qualifying, I hustled to the pre-grid to make sure I was the first car out. Straight out of the pits, I went flat out to get some distance on the Porsches to be able to push the car for the entire time I was out qualifying. As I watched the lap timer in the Mazda 3, my times kept dropping lap after lap. 6 laps in and I had already bested my fastest lap time at Portland by a second, so I called it quits and pulled in to the pits.

On the way out of the track I grabbed the time sheet to review and see where I placed. A quick review of the sheet showed I had qualified the Mazda 3 in second out of 10 cars and I was in front of 2 of the Porsches.

The start of the race didn’t go that great. Out of all the cars on the track I was in the bottom ½ for horsepower. But I was making up the speed in the corners.

One of the back cars jumped the start a bit and managed to take us 3 wide into a corner which is only good for 2. I was forced to give up some room to one of the Porsches to keep from having contact which put me back to 4th. Several laps into the race one of the Porsches who got ahead of me at the start spun off the track so I was able to move back up a spot while trying to chase down the leader who was running ~1 second a lap faster than I was. The 30 minute mark came pretty quick, and the race ended on a not-so-exciting note of me being in 3rd, and the leaders ~ ½ a lap ahead and all but a few of the rest of the field being lapped.

The big question you all want to ask is: “What were you testing for the 3rd Gen Mazda 3?”

First things first, the changes we made to the Mazda 3:
  • We made an adjustment with the CorkSport rear adjustable swaybar. Being able to make quick adjustments on the rear swaybar bar allows us to soften the suspension to match the alignment changes.
  • We had taken more rear camber out of the back of the car with the CorkSport adjustable camber arms, trying to decrease rear grip (yes you read that right). We have been having problems with front end push (understeer) so we worked on dialing rear grip out of the car.  – We had the CorkSport front camber plates maxed out for camber to the class limits, but it wasn’t enough to offset the rear grip.
  • We originally were running our CorkSport Mazda 3 adjustable shocks on the track but we had to remove them as they are not legal for the Touring 4 class. The adjustable shocks make a world of a difference over what I have to use on the car and I wish we could’ve changed back. Being able to fine tune the Mazda 3 suspension is a great asset for any performance driver.

Now to the fun, what I got to test that was new:

The engineers here at CorkSport have been working on a revised Mazda 3 Rear engine mount for the 3/6/Cx5 over the past few months. The best way we have to extreme test parts is on the track.

Think of the race-testing this way: I am driving full throttle, banging gears, and when I am off the throttle means I am on the brakes, so there is no time for the mount to get any rest. There is the maximum amount of heat, load, and stress in a compressed time line, compared to street driven cars, so if failure is to occur it would be on the track.

At the end of the month, I will be doing a test on a final version of the rear engine mount at the SCCA Runoffs and competing to bring home a National Championship for CorkSport and Mazda.

This brings me to my next point: All of the parts mentioned above have been punished on the track and had zero failures. I have been on the same rear sway bar, rear camber arms, camber plates, and short ram intake, and cat back exhaust since we started racing the car at Daytona in 2015.

You just can’t beat the fact that our CorkSport parts walk the talk when pushed to the extreme, which means they won’t let you down, no matter what you’re doing.

Charge for the WIN!

We want YOU to help us design the next CorkSport Branded Ride!

As if it wasn’t obvious, we have a plethora of vehicles to work with around here. True to fashion of course, we at CorkSport have gone and done it again: We went and filled some of the last remaining shop space with ANOTHER CAR.

Not just any car. Say “Hello” to our newest addition: 2018 Mazda 3 Hatchback, touring 2.5L SKYACTIVE-G. Equipped with an automatic transmission and some of the nicer creature comforts.

We love the sparkle of the Eternal Blue Mica and of course her 18” gunmetal dancing shoes. However, as with all things good and standard in the world, we couldn’t help but think that the potential for upgrading is endless.

Do we strip it and go full race car? Perhaps something crazy and AWD swap of sorts? Or maybe we take it way out of left field and go rally-style with it?

With the opportunities being endless, it was starting to make our heads hurt, so we decided to take a step back and start with the basics. We asked ourselves:

“How would our average customer who just picked this car up dream of modifying it?”

And that is exactly what we are doing.

If you guys are anything like us, then you have several hobbies that extend beyond just cars. Some of our team’s personal favorite other hobbies include hiking, camping, traveling, water sports, chilling at the beach, and has recently included obstacle course racing. With all these interests taking up different aspects of our time, we would need a ride that can accommodate our lifestyle. While it would be awesome to have a 6-second drag car, we’d probably have to lose some creature comforts or find a pot of gold to cover the cost, and that’s just not what the average Mazda enthusiast is about.

This project, like we said, is for YOU. And if it’s for you, then we need your help in putting it together.

This car, or as we are designating it: “Project CBR” (CorkSport branded ride), will be built by the people for the people.

We are going to take you with us on the full journey of this car; from the basic mods to the full on weekend task. From the daily driver to the long road hauler. From the car wash to the full service details. We are going to show you everything and anything on this car.

And through the whole process, everything is going to be built with your help.

Over the next several months as we put some miles on our test mule, we will want your guys’ feedback.

  • Do we put springs and shocks on it or full coilovers?
  • What type of wheels should we get?
  • Tint the windows, wrap it, get rid of the chrome?
  • The list goes on!

Every couple of weeks, we will keep you updated on where the car stands and what you think we should do next.

We will create a section on the CorkSport site so you can follow along, ask questions, provide suggestions, and fully immerse yourself into the car. Ever so often, we will also host a poll and you guys will vote on what happens next!

Think reverse sponsored: Instead of CorkSport’s name being the only one on this ride, we will be giving Sponsorship Cred to the Mazda Enthusiasts who give us the ideas for our mods. (first come, first credits).

We’ll put YOUR NAME on the CorkSport Branded Ride.

If you have a Dream Mod, and We pull it off on the CBR, you’ll get the credits… Remember: The CBR is By the People, For the People!

Stay Tuned, we’ll need your feedback soon!
