Unlock reliable boost control and sharper throttle response on your BMW 335i with the N54 twin‑turbo straight six. This premium aluminium charge pipe assembly from Forge Motorsport arrives complete with twin atmospheric valves for exceptional flow and rock‑solid performance. It is a direct connection to the throttle unit and is the go‑to upgrade for enthusiasts looking for a durable boost pipe and BOV solution on their 3.0 petrol 335i.

Designed for serious airflow, each valve features a huge 50 mm aluminium piston. There are no diaphragms to split, and the internal sealing uses heat stabilised Viton o‑rings with high temperature lubricant for minimal wear and long service intervals. Thanks to the low restriction design, operation is refined and noticeably quiet compared to smaller, restrictive valves.

We have fitted this kit on customer cars at MJ Modifications and the feedback has been outstanding. It is a dependable, high quality chargepipe and dump valve package that delivers confidence under boost.
