Forge Motorsport uprated recirculation valve kit for the N54 (twin turbo) as found in the E8X 135i, the E9X 335i and the E82 1M Coupe. Also fits the E60/61 535i.

The Forge valves used in this kit are very similar in terms of operation to the OE Bosch valves used on the N54 – hours of development went into Forge’s existing proven designs to convert them to work seamlessly with BMW’s unique connection mechanism.

The entire valve assembly is precision CNC-machined from T6-6061 billet aluminium, using an aluminium piston design which offers significantly improved durability over the failure-prone OE diaphragm parts.

Capable of reliably handling much more power than the standard parts.
