Forge Motorsport FMBM335DV1 Single Valve Hard Pipe Kit for BMW 335i

Compatible with BMW 335 models equipped with the N54 twin-turbo engine, this rigid alloy hose mounts to the throttle body and incorporates a high-flow open-loop blow-off valve from Forge Motorsport. This turbo valve, fresh from Forge's R&D workshop, is the largest blow-off valve Forge has manufactured to date. Featuring a 50mm aluminum piston, which prevents diaphragm failure issues, the limits of this blow-off valve have yet to be found! The piston O-rings are made of Viton and lubricated with high-temperature grease to ensure a long service life with minimal maintenance. In the box:

1 FMBM335DV1 valve

1 alloy throttle body hose

1 silicone reducer

2 straight silicone hoses (25 mm)

2 30 mm clamps

1 90 mm clamp

2 M6 x 12 Allen screws

Note: thanks to its 50mm piston, the flow rate is very high and unrestricted, and this blow-off valve is very quiet.
