BMW 135i / 335i / X1 (N54 / N55) 50mm Chargepipe Upgrade Kit | Boosted Mentality Motorsports

Eliminate one of the N54/N55’s weakest links and gain improved throttle response and reliability with the Boosted Mentality Motorsports 50mm Chargepipe Upgrade Kit. Designed specifically for 50mm blow-off valves like TiAL, Turbosmart, and others with a 50mm flange, this chargepipe is the ideal solution for high-boost or upgraded turbo applications.

Constructed from durable powder-coated aluminum, this pipe features a CNC-machined billet throttle body flange and uses the OEM c-clip for a secure, leak-free connection—superior to traditional clamp-and-coupler setups. Two integrated 1/8” NPT bungs come pre-plugged but are ready for water/meth injection setups whenever you're ready to dial up performance even further.

This kit includes all necessary hardware, couplers, and caps for easy installation—no custom fabrication required.
