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.

We guarantee that the CorkSport Intake Manifold will give you the best performance out there, but if for whatever reason you’re not satisfied with the unique look of your IM, please contact us and we’ll be more than happy to take care of you like we always do. – We’ve got your back!

  1. We haven’t tried it on a Cx7 yet. Based on what we have seen with other modifications which carry from the MS3/MS6 to the Cx7 it “should” work but we don’t know for sure.

  2. Does this intake take a custom tune for the added flow? And if so are there maps available? Short ram air intake, high flow intake pipe, upgraded fuel pump internals, thanks.

  3. What gain were seen on stock turbo with the intake manifold?
    I’m also interested in the gain of the cams on stock turbo?

  4. Most definitely this will need a custom E tune or dyno tune.. 70Cfm over stock is a huge difference. An Accessport and HPFP are a must otherwise you’ll lean out and toast the motor. Props too corksport another awesome product.

  5. I’d definitely like to see an AUX setup and fuel rail come to market to fit this… One stop shop for more fuelz! Come on Corksport! : )

  6. If that’s ya chick, then why she texting me?
    Why she keep calling my phone speaking sexually?
    Every time I’m out, why she stressing me?
    You call her Stephanie?
    I call her MAZDASPEED, Ooouuu!!!

  7. What gain were seen on stock turbo with the intake manifold?
    I’m also interested in the gain of the cams on stock turbo?
    What fuel was used to reach 378HP?

  8. Hi I would really like to order some parts from you guys I live in Vancouver Canada can I order parts for my Mazda three GT 2018 cold air intake system corks

  9. How will this single runner manifold perform on a stock head that maintains the original dividers untouched? Any drawbacks? I’ve been told that there could be a chance of gasket failure since there is nothing touching the divider section of the gasket on both sides.

  10. Holding off on buying the CS 72 mm throttle body until you awesome people roll out the intake mani again. Other vendors; CPE, Edge and some others offering one just don’t compare to CS level of attention to detail so I’m not sold on theirs.

    Just letting you know we’re anxiously awaiting your IM upgrade!

  11. Hi. Will this manifold be coming back in stock anytime soon?
    Waiting anxiously for its return.

  12. Intake Manifold that is. Very interested in the exhaust manifold. would love to buy both!! Thanks so much for developing the EM also. Well done.
