Keep the boost flowing through your BMW with the Mishimoto 2015+ BMW F8X M3/M4 Charge Pipe Kit. The air-to-water intercooler keeping IAT?s low is a system, and the stock charge pipes can be a weak link. Once the pressure is on, it?s not uncommon for the factory pipes to split at the plastic welds by the turbo or completely burst along the seam, leaving you with a frustrating boost leak. The Mishimoto F8X M3/M4 Charge pipes are a durable, full aluminum construction, expertly TIG-welded for a secure channel for the S55?s boost. Our charge pipes are specifically designed to deliver optimal airflow with a more uniform shape from turbo to intercooler without sacrificing fitment. Our charge pipe kit also includes a pair of matte black silicone couplers for a secure and OEM styled connection to the air-to-water intercooler. The Mishimoto 2015+ BMW F8X M3/M4 Performance Charge Pipes include the Mishimoto Lifetime Warranty for a worry-free installation.
