Suitable for the BMW E82 E88 135i & E90 E91 E92 E93 335i fitted with the N54 Twin Turbo engine. This alloy hard pipe fits to the throttle body and incorporates our high flow blow off valve. This valve, fresh from our R&D department, is the largest displacement valve that Forge have ever made! Featuring a 50mm (2”) aluminium piston so that there are no issues with split diaphragms, we have not found the power handling limits of this valve yet!

The piston uses heat stabilised Viton o-rings and high-temperature grease to ensure a long life with minimal wear and very long service intervals.

Note: that due to the high flow (and low restriction) offered by the 50mm valve, they are very quiet in operation.

We recommend the option Blue Spring + 6.3mm Shim (-10 PSI) for most N54 application, unless you have measured your vacuum pressure reading and are producing much more or much less than than 10psi, this should be taken at normal operating temperature whilst the engine is idling with a pressure gauge for accuracy. 

You can also add the optional 10mm Shim with your order, with this additional Forge 10mm Shim, you can switch between 10psi and 11psi depending on your requirement. 

Please Note: In order to determine the correct spring needed, you will need to measure the inlet manifold pressure.

You may wish to consider the replacement OEM C-clip and O-ring if your stock one is missing, damaged or perished.
