The First and Only Performance Mazdaspeed Throttle Body with NO Sacrifices

Many have tried, but few have succeeded to retrofit or modify an existing throttle body to work with the Mazdaspeed DISI MZR platform.

As you know, CorkSport does things a little differently, and as a result, we started from the ground up to create the best performance throttle body possible with no sacrifices to drivability or reliability. Introducing the CorkSport 72mm Throttle Body for 2007-2013 Mazdaspeed 3, 2006-2007 Mazdaspeed 6, and 2007-2012 Mazda CX-7.

Starting from the ground up means 100% brand new parts, no reworked or refurbished components anywhere.  

We start with an aluminum investment cast body that is made to our specific design specifications.

A flat faced throttle plate is added to gain a little bit of extra flow by avoiding the bump of a traditional round pivot shaft.

Finally, new electronics are added that are based upon OE logic to avoid any tuning and calibration issues.

To retain easy installation, we knew we had to keep the OE bolt pattern. With this, we wanted to maximize the throttle plate diameter for maximum flow. We ended up increasing from 60mm to 72mm. This may not sound like a huge increase, but the OE Throttle Body fits inside the CorkSport Throttle Body with plenty of room! The 72mm size also fits well with both 3” and 2.5” intercooler piping to fit almost any TMIC or FMIC setup. Finally, we did away with the OE gasket (which is too small anyway) and replaced it with a durable O-ring that will hold up to oil, gasoline, methanol, and other fueling options that it may come in contact with.


The CorkSport Throttle Body underwent extensive testing to ensure that it will not fail during daily use and to ensure it performs as well as we expect. The throttle plate underwent endurance testing to validate the D-shaped pivot can stand the test of time. During flow bench testing, we found that the CS TB flows about 150CFM (~33%) better than the OE throttle body when 75% open (accelerator pedal fully depressed).

Check out the graph below for the full data.

In daily driving testing, we noticed better throttle response with no CEL or choppiness. In power testing with a midsized turbo (~GT30 size) we found the throttle body caused faster spool, but when we moved to a big turbo, things got interesting. With a GT35R, the CorkSport Throttle Body caused 100-200RPM faster spooling and an increase in power. Check out the dyno graph down below to see the difference between the CS Throttle body (blue) and the OE throttle body (green).

Each throttle body ships with fresh stainless steel mounting hardware, a 3” stainless t-bolt clamp, and your choice of silicone. We have options for FMIC, MS3 TMIC (which also works for you CX-7 guys), and MS6 TMIC.


If you’re looking to take your Mazdaspeed3, Mazdaspeed6, or CX-7 to the next level, or squeeze that last bit of power out of your big turbo build, the CorkSport Throttle Body can help you meet your goals.

We are constantly searching for ways to improve your experience with CorkSport. Many times we re-visit our parts to see what we can do to improve them; lately we are also starting to turn our attention to improving the instructions that our parts come with. You’ll notice the change starting with our latest products and also some of your favorites. We recently upgraded the instructions for all of our Mazdaspeed 3 intakes to fill them with more pictures and easier to understand steps. Here’s an example:

Instructions

 As you can see, the pictures are full color with easy to find call-outs of key items and steps. In addition to coming printed out with every CorkSport part, you will find them easy to link to on every product page and easily viewable on any computer, tablet or phone. Just one more way that CorkSport has your back!

Product Release! CorkSport Redesigned Turbo Inlet Pipe

CorkSport is pleased to announce the re-release of the CorkSport Turbo Inlet Pipe for the Mazdaspeed 3, Mazdaspeed 6 and CX7. The newest version of our turbo inlet pipe has been redesigned to provide seamless fitment with OEM or other aftermarket intake systems by replicating the fitment of the factory TIP to the intake.

This popular product maintains its ability to provide improved responsiveness and power while now providing even better fitment for customers running stock or other another non-CorkSport brand aftermarket intake.

Unlike other turbo inlet pipes on the market, CorkSport’s Turbo Inlet Pipe is constructed from mandrel bent aluminum making it a true high performance turbocharger inlet pipe. It has been designed with a downstream recirculation valve fitting to prevent turbulence backwash around the MAF sensor and avoid unnecessary check engine lights and stumbling.

During extensive testing, the CorkSport Turbo Inlet Pipe showed a 14% improvement over the stock pipe and significantly decreased airflow turbulence by removing the restrictive nature of the stock pipe with the sweeping curves associated with the mandrel bent aluminum 60mm piping used in the CorkSport pipe.

CorkSport has designed the turbo inlet pipe to be purchased as a standalone piece to compliment your current stock or aftermarket intake set-up or can be purchased with the CorkSport Mazdaspeed 3 Short Ram Intake for the best value on the market.

When combined with the CorkSport Mazdaspeed 3 Short Ram Intake, flow test results showed a 54% improvement over the stock air box and turbo inlet pipe and netted max gains in dyno testing of +25lbs of torque and +33HP.

Sold separately the CorkSport Turbo Inlet Pipe can be purchased for $109.00 and can be customized to compliment the look of your engine bay with polished or powder coated black aluminum piping and your choice of red, black or blue silicone. Purchase the CorkSport Short Ram Intake along with the turbo inlet pipe for an additional $140.00 to get the most gains from this power modification.
