MMR Charge Pipe Kit – BMW 320i, 328i, 420i, 428i, 125i Manual F-Series N20 Turbo. The MMR High-Flow Charge Pipe Kit will improve performance, reliability and even aesthetics of your 2.0 turbocharged 4-cylinder N20-powered BMW F2x or F3x. With increased boost pressure the standard pipework is prone to splitting or cracking – the MMR aluminium replacements ensure reliability, even at significantly increased power outputs. With increased boost pressure the N20’s cheap standard plastic pipework can be prone to splitting or cracking – it’s more a question of’if’ than’when’ you’ll experience boost leaks. By fitting the MMR lightweight aluminium replacement Charge Pipes you can be assured of reliability even at significantly increased power outputs. The smooth bore mandrel-bent pipework has been CFD-optimised to ensure greatly improved airflow versus the OE setup. The rigid pipes also prevent any deformation of the pipes under load or vacuum, another problem that the OE pipes can suffer from. This focus on ensuring smooth flow ensures that the MMR charge pipes will not only improve reliability, but 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 just as good as they fit and perform, and are an easy fit, direct-replacement for the OE pipework. As an added nice detail, the hard pipes also feature a handy 1/8 bung for the easy addition of either methanol, or water injection. The MMR High-Flow Charge Pipe kit includes all you need for installation: three high-flow aluminium charge pipes with CNC leak-free connections, four silicone coupler hose, c-clip and required jubilee clips. WHAT’S IN THE BOX? Three high-flow aluminium charge pipes with CNC leak-free connections. Four silicone coupler hoses.
