Description
Add performance and style while protecting your turbo with the Patent Pending CorkSport Mazdaspeed MZR Bypass Valve. Using an innovative patent pending design utilizing a wave spring, we were able to reduce the spring height of the OEM Bypass Valve by 50%. This size reduction provides the same amount of force while accelerating the speed of the valve. By increasing speed the Bypass Valve effectively increases the life of your turbo by preventing premature wear since the BPV can safely move at speeds 33% faster than stock or other valves. With the extra space allowed by the spring, we were able to increase piston size by over 30%. The increase in size means the bypass valve has a larger venting area, which reduces the time it takes to vent air, allowing larger turbos better venting. Together the smaller size of the spring, and the piston redesign means the body of the valve was reduced. This means you don't have to worry about interference with key parts such as airboxes, custom turbos, intercooler kits, or other modifications that might need the room. Thanks to these innovations the patent-pending CorkSport Mazdaspeed MZR Bypass valve will be a welcome addition to any turbocharged engine bay.

Amazing product!! Easy installation and it sounds great! The video doesn't serve justice to this bypass valve. It sounds very good in person. Highly recommended for anyone that has a Mazdaspeed3/6.

Super easy install, quality sound but yet not too loud. Holds boost well: my cobb log said I'm hitting 16.79psi, on a stg1 tune for 93oct thats suppose to peak at 16.5psi. Keep on making speed3 parts for the 1st gen! thanks yet again corksport for your excellent products and support!

Has this been tested on the corksport fmic? How does it sound and perform with the fmic? CorkSport Reply:It has been tested with our CS FMIC and it works great. The sound is a good sounding whoosh.

Again another awesome product from Corksport. High quality, easy install, big improvement, now that this is on my car the BPV leaking has stopped, So I am getting much quicker spool and alot better holding of boost.

I cant believe how much boost my stock valve was leaking! I thought my boost gauge was just crappy but after I installed this, I finally hit target levels! not only that, but I love how small this is!

does it require tuning???...I plan on getting the bypass valve along with stage 2 intake... CorkSport Reply:no tune required with the valve install.

Is this better than the forge bpv? Which one has a louder noise? I still have the stick intake.
Sam
Would this BPV work better than the Forge with my Corksport SRI? CorkSport Reply:Give us a call, the term work is pretty broad.
