Forge Motorsport Charge Pipe for BMW 2 Series M235i N55 (F22/F23) – Turbo Outlet/Boost/Intercooler Pipe, Aluminium Hard Pipe with WMI/Meth Bung – Replaces OE 13717604033

Aluminium turbo outlet tube upgrade for BMW 2 Series M235i F22 F23. Replace the fragile factory plastic pressure pipe with a robust, powder coated hard pipe that is built to handle increased boost and spirited driving. This is the reliable solution for N55 owners who are tired of split couplers, cracked plastic ends and sudden boost leaks.

We have fitted this part on our own builds and for many customers, and the feedback is consistently positive. Sharper throttle response, reduced turbo lag and peace of mind from a far stronger charge air path. It is a straightforward swap for the OE duct and keeps all the functionality you want.

Why upgrade

The OEM plastic charge-air tube is a known weak point on N55 cars. The throttle body coupler can become brittle and fracture, leading to boost loss and limp mode. This alloy hard pipe uses a billet CNC connector that locks into the factory O-ring style flange, creating a durable, serviceable and leak-resistant join. It is the ideal foundation for tuned setups and a smart preventative upgrade on standard vehicles.
