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.

I bought this back in 2014 and till this day still works like a champ. It really helps a lot in the way it recirculates the air.

Worked fine for about 2 years, then the wave spring broke in 2 places. still sort of worked and took a bit to figure out why the release had become so sudden. MS6 is stock except for SRI, and boost is never over 15.5. Unreliable.

Happy to have purchased this gem, very easy to install; I drive a 2008.5 Speed 3. I also purchase and installed the silicone bpv hose at the same time.

I have a 2012 Mazda 3 MPS (Mazdaspeed 3). Installed this about 10 months ago and did around 15,000km on it. I've got a stage 1 custom tune with intake mods only. About a week ago, I noticed a drop in performance with an audible whistling noise whilst on the throttle at low RPM (which I'm pretty sure was boost leaking from the BPV). Venting sound of the BPV also became more drawn out (as opposed to a quick, efficient whoosh). Removed the BPV and opened it up to have a look and found that the spring for the piston was completely broken into 3 parts. My car is driven sensibly and not thrashed. Not happy at all with the quality. Purchased a Turbosmart Kompact BPV and installed today and the car feels great again. Puts me off buying more stuff from Corksport. Don't usually like to leave negative reviews but this really irked me, sorry. Better off buying a cheaper valve in my opinion. ***CorkSport Reply: Kev W contact us so we can help you out via telephone or via email contact here on our webpage ***

Quieter than stock, but wow does it perform!

Super easy to install, make sure gasket is lined up and just torque down to 7 ft/lbs(80-85 inch/lbs), transfer the vacuum/boost hose from the plastic OEM BPV nipple to the CS metal (super strong never gonna snap) nipple along with the bypass hose and yer set for s\anything but a crazy 10k engine/turbo build. Fast response, good reliability, some increased turbo life. And full Sleeper Action. Gotta love it!

LOVE the new sound this BOV and SRI added to King_6. I only wish the blow off could be louder... Thanks CS! Next in line is my fuel pump internals. #MazdaAllDamnDay

Awesome product. Much crisper pressure release and sound compared to stock BPV. Very happy with this BPV. Highly recommend!

Great looking piece of kit. I dig it. Love the sound of it. The buttometer says the throttle response is more linear, particularly at the lower end, and the power seems to come on a bit stronger and carries through the revs nicely. Recommended.
