MMR Charge Pipe Kit – BMW 320i, 328i, 420i, 428i, 125i Manual F-Series N20 Turbo. With increased boost pressure the standard pipework can be prone to splitting or cracking, with the MMR lightweight aluminum replacement pipes 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 reducing any deformation of the hoses under load or vacuum, the MMR charge pipes also improve throttle response and ultimately, power output. Finished in a durable crinkle black finish – contrasted by laser-etched MMR logo detailing, the MMR charge pipes look as good as they fit and perform, are a direct-replacement for the OE pipework and include four silicone coupler hoses, c-clips and required jubilee clips. The hard pipes also feature a handy 1/8 bung for the easy addition of either methanol, or water injection. Three high-flow aluminum charge pipes with CNC leak-free connections. Four silicone coupler hoses. If there will be any delays in your order you will be informed within 24-48 hours. Image for illustration purposes only. Distributed By Haz Motorsport.
