The APR Charge Pipe System is a comprehensive, direct replacement upgrade, to the factory system. We upgrade the factory plastic pipe with a strong 60mm aluminum pipe. Due to the thin-walled nature of metal vs plastic, we're able to increase the internal diameter of the pipe to maximize airflow. The MAP sensor mounting point is made from CNC-machined billet-aluminum. All brackets are TIG-welded for a strong and precise fit, and the pipe is coated black. A protruding lip at the edge of the pipe helps prevent hose slippage. This pipe is a direct fit to the APR or OEM throttle body hose, as well as the APR or OEM intercooler hose. APR recommends upgrading the throttle body and intercooler hoses as well for maximum performance and reliability.
