Color: Black OnlyTurboSmart developed this ultra high quality Bypass Valve (BPV) Kit EXCLUSIVELY with Street Unit Performance, Inc. This valve features a machined billet aluminum body and includes your choice of a standard pressure spring or a high pressure spring. 100% of the pressure released is recirculated back into the intake just like the stock configuration. This BPV is available in a anodized satin black finish for a sleek, clean, OEM presentation.

This valve will give you improved throttle response, boost handling capacity, and quicker spool recovery over the stock plastic valve. This means increased performance and efficiency over the OEM valve!

Installation is simple, the BPV bolts right up to the stock mounting location and does not require cutting or any other alteration to stock components! Installation takes less than 10 minutes with minor tools.

This is the perfect valve for anyone that wants the reliable performance gains of a TurboSmart valve with a sleeper design!

Select Spring Option: This valve has two spring options, standard spring or a high pressure spring. The Standard Spring pressure is rated at 10-20 PSI and the High Pressure Spring is rated to handle 20-25 PSI efficiently. Springs are easily interchangable and offered seperately for future upgrades. Both springs were developed for the Mazdaspeed/MPS vehicles.
