Introducing the long-awaited CorkSport Intake Manifold for the DISI-MZR engine found in the Mazdaspeed 3 and Mazdaspeed 6.

First impressions will quickly tell you this is a very different design and design goal than typically found in the performance aftermarket options for the MS3 and MS6; that’s for good reason.

The CorkSport Intake Manifold is a combination of performance and OE fitment without compromise.

Equal flow, higher flow, tighter packaging, and TMIC fitment are aspects that define the CorkSport Intake Manifold. #ZoomZoom!

Check out the video below. Share your performance review with the CorkSport community once installed!

Fitment Inspired

We know modifying additional components to install a new performance part can be a real PITA; we worked hard to design a performance intake manifold that does not require extensive modification to use. The CS IM installs nearly identical to an OE IM plus difficult to access hardware locations on the flange have been clearanced for improved installation.

The following components are in OE location and install like OE:

    1. 70mm Throttle Body Opening
    2. Oil Dipstick Mount
    3. MAP Sensor
    4. PCV Port w/include Barb Fitting
    5. Top Mount Intercooler (TMIC) Mounts (hardware not included)
    6. Lower Mounting Brace

Design Focused

The CorkSport Intake Manifold may fit like OE, but that’s where the similarities end. The CS IM is designed with performance and drive-ability in mind with the larger plenum design and long even flow cylinder runners.

The intake plenum is ~3x larger than OE which improves high RPM power capacity without sacrificing throttle response and drive-ability. The cylinder runners are longer than the typical aftermarket intake manifold to improve mid-range power while still having peak RPM capacity with the single runner design vs the OE split runner.


Balanced Flow

Balanced flow is critical to the durability and performance of an engine; this is why the Intake Manifold is such a valuable performance component for the Mazdaspeed engine. The OE Intake Manifold has significant flow imbalance between the 4 cylinders which causes cylinders to run excessively lean or rich, affecting engine durability and performance.

Check out the graph to see the difference. Not only does the CS Mazdaspeed Intake Manifold outflow the OE design by 70CFM 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.

    1. CorkSport Intake Manifold: 275CFM per Runner Average @ 2% Imbalance
    2. OE Intake Manifold: 205CFM per Runner Average @ 21% Imbalance

Performance Driven

The increased flow capacity and even flow between the cylinders provided by the CorkSport Intake manifold help increase power across the entire RPM range and spool the turbo ~100 RPM faster than OE. The graph to the right shows the difference in power before and after the CS IM on a MS3 with the CorkSport TD05H-18G turbo equipped.

The horsepower spike around 3300rpm is a result from a combination of the CS IM for the mazdaspeed3 and mazdaspeed6 and a small increase in wastegate pre-load. The increased efficiency of the CS IM caused a 2-3psi drop in boost pressure that had to be corrected with the wastegate preload.


Bonus Power Potential

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

    1. First off is the larger throttle body opening measuring at 70mm vs the OE 60mm. This works great with the OE throttle body and also allows the use of a larger throttle body without modification if desired.
    2. Second are the additional fueling ports located on each runner. These are standard 1/8-27 NPT threaded ports that can be used with methanol nozzles or other fueling options.
    3. Lastly there is an additional 1/8-27 NPT vacuum/boost port for gauges, controllers, etc.

Hardware & Accessories

The CorkSport intake manifold comes to your door with the installed hardware as well as additional hardware and accessories required for installation. This includes:

    1. Two – M8x1.25x35mm Flange Bolts
    2. Four – M6x1.0x55mm Socket Cap Bolts
    3. 1.5 Ft – 1/4” ID Chemical Resistant Rubber Hose for the EVAP System
    4. 2.5 Ft – 3/8” ID Chemical Resistant Rubber Hose for the Brake Booster

  • Vehicle Fitment: 2007-2013 Mazdaspeed 3 and 2006-2007 Mazdaspeed 6. 2007-2009 CX-7 Not Confirmed
  • Designed in America: Designed in Vancouver, Washington, in the Pacific Northwest.
  • CorkSport Service & Support: 2 year limited warranty, full color installation instructions, all necessary components, and knowledgeable telephone support at (360) 260-2675.

  • The CorkSport Mazdaspeed3 Intake Manifold / Mazdaspeed6 Intake Manifold is for off-road and racing applications only.
  • EGR Block-Off Plate: The CorkSport Intake Manifold does not retain the EGR recirculation port. An EGR block off plate is required for installation.
  • a. This will cause an CEL (check engine light)
  • VTCS: The CorkSport Intake Manifold does not retain the provisions for the VTCS system.
  • a. This will cause a CEL (check engine light)
  • Gaskets Not Included: OE throttle body and cylinder head gaskets are not included in the kit. OE gaskets will work correctly with the CS IM.
  • a. OEM Intake Manifold Gasket – Part #: L3K9-13-111 b. OEM Throttle Body Gasket – Part #: L3K9-13-655
  • Due to the difficulty of the manufacturing process, no intake manifold is identical or perfect in reference to the casting. Dimensionally and performance-wise, the intake manifold will perform as advertised. Every intake manifold is inspected for quality assurance. However, if any customer is unhappy with the aesthetic/look of the part, call us before installation and we’ll be happy to take care of you.
  • Tuning: the CorkSport MS3 Intake Manifold requires aftermarket tuning for proper engine performance.

Absolutely love this intake manifold. Install was less of a pain than an OEM PnP manifold. Works flawlessly with Corksports throttle body. Dropped my LTFT from 16.x down to .7!
Car feels amazing after the installation. The acceleration is so much better and a very noticeable difference. Highly recommend this to any Mazdaspeed owner.
Instructions are great and an easy install.
I beta tested this manifold on a built motor, ported head with a 6266 spraying methanol. Install was a breeze and the power came on quick and the power held until my redline of 7600rpms. Great flow and great look. Solid quality piece!
Even flow and a lot of it. My car picked up 14 g/s on the same map with no changes. Fitment on this piece is outstanding - it's easier to install than the OEM and clearance blows away the competition. It has a slew of vacuum and meth bungs, making this perfect for someone wanting ~550 wheel horsepower (that's about the limit of the typical methanol pump). A knife edge PI spacer would be a great option for those wanting even more fuel and crazy boost.
