Product Information

We 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.


In The Box:
1 x FMDVK04SA Valve
1 x Uprated Yellow Spring
1 x Uprated Blue Spring
1 x Uprated Red Spring
1 x Forge Sticker

Please note: In certain car models the removal fo the O.E mounting bolts may be better facilitated by grinding down the short leg of the appropriate Allen key to 10mm long.
