Masata BMW N54 Aluminium Charge Pipe with Genuine HKS BOV (Blow Off Valve) - Fits E82 1M, 135i (E82/E88) & 335i (E90/E91/E92/E93, xDrive) - Black CNC, 1/8 NPT Meth Bung, OEM Fit

Masata N54 Boost Pipe Kit with Authentic HKS Blow Off Valve for 135i, 335i, 1M

Stop boost leaks and unlock sharper response on your twin-turbo BMW. This Masata alloy boost pipe replaces the brittle factory plastic ducting with a strong, lightweight aluminium hard pipe and includes a genuine HKS blow off valve for crisp vent-to-atmosphere sound and reliable boost control. Precision CNC machining ensures a perfect throttle body seal and true OEM-style fit, finished in stealth black for a factory plus look.

Whether your goal is reliability on a stock car or consistent performance on a tuned setup, this uprated pressure pipe is a proven fix for split plastic pipes and unexpected limp mode. Expect faster spool, improved throttle feel and dependable boost holding under load. It is a smart preventative maintenance upgrade on higher mileage N54 engines and a must-have when raising boost.
