MMR Aluminium Charge Pipe Kit – BMW F20 F30 B48. MMR’s high-flow charge pipe kit includes everything needed to improve the performance, reliability, and aesthetics of your B48-powered F-Chassis BMW. Smooth bore pipework improves airflow over stock and due to reducing deformation of the hoses under load or vacuum, the MMR charge pipes also improve throttle response and power output. Increased boost pressure can cause the stock pipework to split or crack and cause drivability issues. MMR’s charge pipes are made of lightweight aluminum which fit right in place of OEM charge pipes. Includes a 1/8 bung for easy addition of either methanol or water injection. Two high-flow aluminum charge pipes with CNC leak-free connections. X3 Throttle body bolts.
