Forge Hard Pipe with Single Valve Kit for BMW 135 – E81, E82, E87, E88 – N54 Twin Turbo

Upgrade your BMW 135 with this Forge Motorsport alloy throttle body hard pipe and integrated high flow blow off valve. Designed for the N54 twin turbo engine, this Forge hard pipe and single valve kit delivers exceptional flow, rapid response and superb reliability. It is a proven performance upgrade for drivers who want a durable charge pipe solution and a quality BOV for their E81, E82, E87 or E88 135 platform.

The included Forge valve is the largest displacement valve Forge have ever made, featuring a 50 mm aluminium piston for maximum flow and minimal restriction. The piston runs heat stabilised Viton O-rings with high temperature grease for long service life, minimal wear and very long service intervals. Thanks to the huge flow capacity of the 50 mm valve, operation is notably quiet while maintaining excellent performance.

  • Low restriction, quiet operation with outstanding flow
