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.

Worth every cent! better response and with more mods I do, I don't have to worry about issues the stock unit may cause like leak and slow response with higher boost levels.

The BPV installed in about 5 minutes with no issues. The car is also running a CS SRI with turbo inlet. Everything else is stock. The car holds boost better into the high RPMs. The car also spools back up between gear changes faster which makes the car faster overall. The sound is slightly sharper than the stock BPV though no louder but with a muted whistle on low-pressure discharges. This was an excellent upgrade to my 2012 MS3.

Was so easy to install, and made a difference for holding boost at low throttle. Wish I had bought this sooner!

Holds boost, sounds like a canary at part throttle, comes apart easily for cleaning. Only gripe is that the 6 screws that hold it together were rusted within 6 months...

All I have to say is WOW. Huge difference. Get rid of your stock valve and get this bad boy. My turbo pulls strong throughout the entire powerband now, didn't know what I was missing out on. Another fantastic part from CS.

This is definitely an outstanding product!!!!! You get performance and sound at the same time. My car is running much stable in boost. Really quick boost recovery due to fast operation of valve. The beautiful black stealth finish is really nice and looks good on the engine bay. I was surprised on how great this valve sounds. For being a bpv not a bov, it sounds pretty pronounced and very aggressive when wot. For those of you who want best performance drivability and a touch of sound, this is the valve for you. I regret not buying it before! No other valve is faster on the market right now! Don't think about it twice, just pull the plug and purchase this valve for your MS3, trust me, you won't regret it. The guys at corksport have an outstanding support, I was called by Spencer a few days after, just to make sure everything with the product was going as expected and this speaks for itself about the outstanding customer service they have. Spencer, Dereck, Brandon etc. they all are great at what they do. Corksport keep on making top notch products. Thumbs up for corksport for such great bypass valve for the ms3.!!!! Ok, you have read all of this review and the rest of the reviews so go do yourself a favor, pick up the phone and place an order for this valve. When you get it, you are going to regret not ever buying it before.

Another great product from this fantastic performance parts specialist. A lot better than the standard BPV, sounds cool too.
Steve Kizer
Great looking product. Easy install. CorkSport had me sold by telling me this product increases the life of my turbo. With all the performance mods, I wanted to take every precaution to keep my engine safe at the same time. Make sure you transfer the stock rubber gasket to your new CS MZR BPV.

I have enjoyed all my corksport upgrades, and this one is no different! Boost holds firm and releases in a very mature sound, quality is superb, and is a super easy install! Buy this for your MS3!
