Replace the restrictive OEM plastic charge pipe and increase airflow and intercooler efficiency with the PERRIN Charge Pipe for 2015-17 WRX.

The CNC machined PERRIN turbo flange adapter uses the same design as the OEM flange on the turbo side of the charge pipe and uses the OEM o-ring for perfect fitment and no leaks, unlike off-the-shelf o-rings.
