Direct Fit Piston Blow Off Valve with Tuning Springs Colour:Silver but we have done justWe recommend servicing your valve every 3 years, or 20,000 miles, whichever comes sooner This is a piston design bypass valve that is a direct replacement for the original fitment. This valve gives greater longevity than the diaphragm (OEM) valves but also benefits from its ability to be fitted with different springs when the boost pressure has been increased or the engine has been modified. To ease installation the top or vacuum connection is angled.
