Masata Alloy Boost Pipe for BMW X3 F25 35i xDrive and X4 F26 35i xDrive, X4 M40i xDrive

Strengthen the pressurised side of your N55 turbo system with Masata’s alloy hardpipe, designed for the BMW X3 F25 35i xDrive and BMW X4 F26 35i xDrive plus X4 M40i xDrive. This robust upgrade replaces the fragile factory plastic pressure pipe that often splits or blows off under load, especially on remapped cars. Expect cleaner boost delivery, crisper throttle response and dependable performance on both stock and tuned setups.

We run this part on our own development car and have installed it for many customer builds. Fitment is spot on, it seals perfectly and it has proven to be a brilliant reliability mod for daily driving and spirited use alike.
