The charge pipe should be the first modification made to your BMW. The Charge Pipe Kit is a direct replacement for the OEM pipe that due to its plastic material is prone to breaking under increased pressure. The MMR Performance Charge Pipe is made from lightweight aluminium and assures a more sturdy pipe that increases the throttle response and decreases the chance of turbo lag allowing you to push the engine further than before, as it’s smooth pipework improves the airflow. With its durable crinkle black finish paired with the laser-etched MMR logo, it really does look as good as it performs. Included in the Kit. Replacement high-flow aluminium charge pipe with CNC leak-free connection. Silicone coupler hose and two stub hoses.
