The MMR high-flow charge pipe kit includes everything you need to improve the performance, reliability and aesthetics of your E90, E92 or E93 N55 engine. With increased boost pressure the standard pipework can be prone to splitting or cracking, with the MMR lightweight aluminium replacement pipe you can be assured of reliability even at significantly increased power outputs. The smooth bore pipework improves airflow versus the OE setup and due to preventing any deformation of the hoses under load or vacuum, the MMR charge pipe also improves throttle response and ultimately, power output. Finished in a durable crinkle black finish - contrasted by laser-etched MMR logo detailing, the MMR charge pipe look as good as it fits and perform, is a direct-replacement for the OE pipework and feature a CNC machined hose end for leak-free installation. Also includes two handy 1/8” bungs for the easy addition of either methanol, or water injection. WHAT'S IN THE BOX?
