MMX Performance F2X / F3X / F87 (N55) Chargepipe Kit

The MMX Performance BMW F2X / F3X / F87 N55 Charge Pipe Kit (Intake Side) is a direct-replacement upgrade for one of the most well-known failure points on the N55-powered F-chassis BMW range. The factory intake-side charge pipe is plastic, and under elevated boost (particularly on tuned cars) it is prone to splitting and cracking. The MMX aluminum replacement eliminates that failure mode entirely while improving airflow, throttle response, and the appearance of the engine bay.

The pipework is constructed from lightweight aluminum with smooth bore internals that flow noticeably better than the OE plastic setup, and the construction also prevents pipe deformation under load or vacuum. CNC-machined hose ends and a supplied silicone coupler hose ensure a leak-free installation. Each pipe is finished in a durable crinkle black powder coat with laser-etched MMX logo detailing, the kit looks every bit as well-engineered as it performs.

The kit also includes a 1/8" methanol / water injection bung, ready for owners running or planning to run a meth or water-meth setup. For owners not running injection, the bung ships sealed and can simply be left alone.

If your N55-powered F-chassis BMW is tuned, headed for a tune, or simply still running the original plastic intake-side charge pipe, this is one of the most important reliability upgrades you can fit to the platform. MMX strongly recommends fitting this kit alongside their N55 turbo-side charge pipe kit (sold separately) for a complete N55 charge-pipe upgrade.
