The Mishimoto F1X M5/M6 Charge Pipes are a durable, full aluminum construction, expertly TIG-welded to ensure a smooth and strong airflow path for the S63's boost. Our charge pipes are specifically designed to deliver optimal airflow with a more uniform shape from turbo to intercooler without sacrificing fitment. To provide the utmost perfect fitment, along with the charge pipes, we also include a CNC-machined 6061 aluminum bracket to hold the metal coolant lines that are supported by the factory intake tubes. Our charge pipe kit also includes a pair of matte black silicone couplers for a secure and stock styled connection to the air-to-water intercooler. The Mishimoto F1X M5/M6 Charge Pipes include the Mishimoto Lifetime Warranty for a worry-free installation.
