Benefits of fitting?
The MMR High-Flow Charge Pipe kit includes everything you need to improve the performance, reliability and aesthetics of your N55-powered 135i E9x.
With increased boost pressure the N55'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.
The MMR High-Flow Charge Pipe kit includes all you need for installation: the high-flow aluminium charge pipe with CNC leak-free connections, silicone coupler hose, c-clip and required jubilee clips.
