Mishimoto Mishimoto Blow Off Valve Setup Spring, White Black (7.25-10.9 PSI) - MMBV-SPR-BK

Tuning your Mishimoto 50mm Blow Off Valve to your vehicle is essential for its proper operation. Too small of a spring and the valve will open at idle and low boost, letting precious power escape to the atmosphere. Too big of a spring, and the valve won’t open when it’s needed. Luckily, Mishimoto offers three setup springs to tailor your blow off valve to your vehicle. We offer these springs for idle vacuums reading 7.25-10.9 PSI (black spring), 5.07-2.25 PSI (blue), or 0-5.07 PSI (white). The blue spring is included with all Mishimoto 50mm Blow Off Valves but is included in this set, in case you need to replace it due to wear or if it decides to make a great escape across the shop next time you disassemble your valve. Of course, like all Mishimoto products, this blow off valve setup spring set is covered by our Mishimoto Lifetime Warranty.
