BMW 335i N54 Charge Pipe and BOV Upgrade by Forge Motorsport
Unlock dependable boost control and serious airflow on your BMW 335i with this premium alloy charge pipe and integrated blow off valve assembly. Designed to replace the factory boost pipework at the throttle body, this Forge Motorsport setup delivers exceptional reliability and consistent performance on the N54 biturbo straight six. It is a robust, precision-engineered boost pipe upgrade that enthusiasts choose for both road and track.
At the heart of the kit is Forge’s high-capacity piston valve with a huge 50 mm aluminium piston. There is no diaphragm to split, the sealing is handled by heat-stabilised Viton seals, and it is lubricated with high temperature grease for long service intervals. Thanks to the very low restriction design, operation is impressively quiet even under heavy load. In testing, flow capacity has proven immense, comfortably supporting serious power without fuss.
