Supply your big turbo Speed6 with plenty of air with a 4 Inch Intake.
Add to wish list

Ready to take your Mazdaspeed 6 to the next level and remove any upstream turbo restrictions then you have found the best option, our 4 Inch Intake. When aiming for the highest power levels you will exceed the MAF sensor flow with smaller air intakes and need a larger intake to feed your speed engine all the air it wants. The Mazdaspeed 6 4” Intake combines the ease of use of smaller intakes with enough flow to support over 900whp. Read below for full details and more pictures.#ZoomZoom!

The CorkSport Advantage

A true 4 inch air intake system for big turbo Mazdaspeed 6

Fitment Focused:

To make the Speed6 4 inch Intake the best, we rethought the way everyone has designed other intakes. The big change is with the MAF housing connection; instead of a silicone coupler to attach the MAF housing, the machined MAF housing is welded directly to the turbo inlet pipe. This gives you latitude to optimize fitment and filter size. You end up with a 4 inch intake that takes up less room than most 3.5” intakes while retaining all OEM mounting points, BPV, and PCV/boost vent ports.

The best Mazdaspeed6 cold air intake

Massive Power Potential:

4 inch intakes offer a bonus power potential. By moving up in intake diameter, you increase the maximum amount of air your Mazda 6 speed can ingest. With a retuned ECU, you also increase the amount of air the maximum the MAF sensor can read. Typically not offering a power bump on lower horsepower Mazdaspeed 6's already with big power can see an increase in power, just by reducing the airflow restriction before the turbo. The bigger diameter increases efficiency & increases the operating range of the MAF sensor to support over 900whp.

Optimized Filter:

The 4” Intake System reduces flow restrictions by using a huge air filter measuring 7 in length x 4.5 inches at the MAF inlet. Air Filter size is something most large intake systems ignore, which can ruin some of the benefits of going to a large intake. A larger pipe size does no good if your air filter flows poorly and/or is too small. We chose the Pro Dry S material for fantastic filtration and flow without the risk of an oiled filter dirtying the MAF sensor. You can see how much bigger this is than our normal filters in the picture!

Accurate Flow:

The Mazdaspeed 4 inch design may be a bit different from our typical intakes, the CS 4” intake still retains a billet aluminum MAF sensor housing. When combined with the pre-installed air straighteners it provides accurate airflow readings. The result is an easier to tune Mazdaspeed 6 ECU and will consistently read the actual amount of airflow entering your engine.

Materials & Manufacturing:

Each CorkSport 4” Intake System is made from mandrel bent 6061 aluminum tubing which ensures strength and smooth airflow into your turbo. The billet machined MAF housing and ports are TIG welded in place for upmost strength and reliability. The Speed6 intake pipe is wrinkle black powdercoated for a clean look that will last and match any engine bay. Also included is your choice of turbo inlet coupler made from 4-ply reinforced silicone. Turbo couplers size options are to fit 4.0”, 3.5”, and OEM sized compressor housings. Stainless steel T-bolt clamps are included to complete the intake kit with everything you need!

  • A tune is required for installation of this intake. Your tuner must scale the MAF sensor to suit the larger diameter MAF housing.

How to install a Mazdaspeed 6 cold air intake

If you are going for a high hp build, this intake is perfect for you. It pairs really well with the CS MS6 FMIC kit. I recommend relocating your battery to the trunk. Depending on your BPV choice, you may have to adapt/build your own recirc tube or eliminate it and put a freeze plug on the recirc tube part of the intake.
5 stars! This intake is a good way! The fitment was great and the 90 degree coupler that connects to the turbo inlet was so easy to install; easier than the old 3.5 inch intake I use to have surprisingly. The textured coating looks great and blends into the engine bay seamlessly. AND THE NOISE OMG its fantastic! My CST5 turbo makes the best sounds with this massive intake and tuning has been cake with the Man Erik @ DramaTune.
