Masata Alloy Boost Pipe for BMW B48 and B46 Engines – Part No. MST0100

Give your turbocharged BMW the robust pipework it deserves. The factory plastic pressure tube on the B48 and B46 is known to fatigue and split on remapped cars, causing boost leaks and limp mode. Masata’s metal boost pipe replaces that weak link with a precision engineered, black coated aluminium hard pipe that holds pressure, flows better and stands up to increased boost targets. Expect crisper throttle, stronger mid-range and rock solid reliability on daily drivers and tuned builds alike.

We run this kit on our own cars and customer vehicles and the results have been excellent. Fitment is spot on, the finish is quality and it simply works. If you are chasing dependable performance from your BMW turbo four, this is a must-have supporting mod.
