The CorkSport Advantage

Mazdaspeed 3 bypass valve

Responsive Performance

The CorkSport Dual VTA BPV responds as low as 50 milli-seconds keeping pressure in check and the turbo spinning freely. This is made possible with a few key features:

  • The piston weighs a mere 38 grams with the O-rings installed which reduces the required force (and therefore time) to accelerate and move the piston.
  • The piston and body design work together to minimize the chamber volume at the top of the piston. With the smaller volume there is less air to be removed before full vacuum is present, reducing the amount of time needed to start moving the piston upward.

No Leaks

O-rings are used for all critical sealing interfaces to provide a valve that can stand up to the pressure and has been tested to 50psi.

Dual VTA-Bypass Design

The VTA design of the CorkSport Dual VTA BPV allows the valve to function as a normal full recirculation design for most daily driving situations; essentially during minimal boost pressures and light throttle lift-offs.

The VTA ports will then be utilized for medium to high boost and abrupt throttle lift-offs. The higher boost levels cause a larger pressure differential between the intake manifold and charge pipe during throttle close, resulting in the BPV piston moving further, opening the VTA ports.

Flexible Design

Standing just 2.5” tall, the CorkSport Dual VTA BPV is compact which is great for compact engine bay and custom intercooler piping. The VTA BPV also features and integrated hose port to reduce the chance of leaks and lost parts.

The nozzle features 3-way adjustability allowing the nozzle to point 15 or 30 degrees off-center.

Performance Throttle Body for 2006-2013 DISI MZR Mazdaspeed (GEN-6-497-10)

The CorkSport Throttle Body for Mazdaspeed 3, Mazdaspeed 6, and Mazda CX-7

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 CorkSport Throttle Body.

The CorkSport Advantage

Mazdaspeed 3 throttle body

Ground Up Approach

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.


Design Focused

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.

Easy Installation

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.

Tested and Proven

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.


Checkout 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.
