Introducing the first and only performance throttle body for the MZR DISI that offers no
By taking a ground-up approach we were able to succeed in making a throttle body that performs better than OE while retaining OE fitment and daily drivability. With easy installation and drop-in fitment, you are sure to enjoy the gains from the Mazda3 Speed Throttle Body.

Instead of trying to enlarge an OE throttle body or adapting to a different vehicle's throttle body to work, we started this project from the ground up. This gave us complete design freedom to make the best throttle body possible. The CorkSport Throttle Body uses 100% brand-new parts. The body is an aluminum investment casting that was made precisely to our CAD-optimized specifications. Coupled with new electronics that are based on the OE logic, the CS throttle body is truly a full OE replacement.
The CorkSport Throttle Body increases the throttle plate diameter from 60mm to 72mm to allow for the maximum flow that can be achieved with the OE bolt pattern. This may not sound like a very large increase, but the stock throttle body opening fits inside the CS Throttle Body opening with plenty of room! To further help with flow, the face of the throttle plate is flat. By using a D-shaped center pivot, the airflow does not have to go around a bump right in the center of the throttle plate. Plus, this design has been endurance tested to ensure that it will stand up to the test of time.
By sticking to 72mm, the OE bolt pattern could be retained. That means the install stays simple and does away with any need for special adapter plates or a different intake manifold. It has been test-fitted and proven to work on OE, CorkSport, and JMF intake manifolds. 72mm is also the optimum size for versatility between 2.5"; and 3"; intercooler piping so it will fit almost any TMIC or FMIC setup. As a final touch, an O-ring groove is machined into the body with an included O-ring so you do not need to re-use the OE gasket (it's too small for the 72mm opening anyway). Don't worry though; the O-ring is safe with oil, gas, methanol, ethanol, and other chemicals that may find a home in your engine.
We have extensively tested the CorkSport Throttle Body and have found that it flows about 150CFM more than OE when the throttle body is 75% open (which is 100% accelerator). This is about a 33% increase over the stock throttle body. That is all well and good but what does it mean? In daily driving, we noticed better response with no CEL or choppiness. When testing for power on a midsize turbo (GT30 size), we primarily noticed that the turbo was spooling at a lower RPM. When we moved to a big turbo (GT35R or larger) we saw 100-200RPM lower spooling and an increase in midrange power.
Check out the dyno graph to see for yourself, blue is the CS throttle body, green is the OE throttle body. Note: there were no changes other than adding the CorkSport Throttle Body.
It will take you one hour to install the CorkSport Mazdaspeed Throttle Body with our easy-to-use instructions.

I want to buy this throttle body but Im really confuse where to reroute the coolant lines. Is there a video or some reference that shows how to do this. Im ready to order but Im just unclear on the rerouting.
At the bottom of the product page is the instructions, you can open them and see how the routing is done.
Does the throttle body come with the appropriate coolant hose(s) to bypass the throttle body or does it need to be sourced independently?
It does not come with new lines, you will need to reroute the existing ones.
Hi , does this come with the throttle body sensor ?
Yes, that sensor is built into the throttle body
i have a 2006 mazda 6 MPS that needs a new throttle body, i cant find a stock one that would ship to finland, and it looks like this is next best option. the car is stock except for corksport SRI and dual bypass bpv. Would you reccommend it or should i keep looking for a stock one?
You can use this in place of the OEM part, nothing else is needed.
Will this fit a Mazda 3 2016 2.0l? If not what are my options
This will not fit the 3rd gen, we don't carry a replacement for the OEM throttle body at this point in time.
Would you recommend this throttle body for stock turbo speed3s? Are the gains noticeable on a KO4 and is it safe?
Yes, with a tune it will add a little more power.
Can use for Mazda CX-5 2.0 2018?
This product is for the Mazdaspeed 3/Mazdaspeed6 and Cx7 Turbo
I'm thinking of buying a throttle body (or rather, I'm going to buy one). My mazdaspeed3 gen2 is an OE throttle body and the connection with the intercooler is an Auto-EXE suction pipe. In this case, which coupler should be selected?
The coupler that matches your OEM intercooler, if that is what you currently have.
Do you need to buy a oem throttle body gasket or it doesn't need
It comes with the necessary o ring for installation.
Is the o ring gasket better to use than your throttle body gasket you offer for high hp (500hp) set up? Thx
One isn't better than the other exactly, just depends on how often you may be taking it apart, and whatever is more convenient for you. The gasket does help to offer some added thermal protection, so its up to you.
Is there a different throttle body for the 2011 Mazda 3 2.5 L Manual Transmission?
We don't offer one for any other vehicle than the speed 3 at this time.
Would this fit the 2011 Mazda 3 2.5L?
Not it would not
Section 3 in the instructions makes no sense. What am I supposed to do, disconnect the hose and then reconnect the same hose?
The coolant hose feed will be disconnected and then plugged back into the return to that it bypasses the throttle body.
