OVERVIEW

Replace the factory intercooler piping with the K&N 77-1018TWR Charge Pipe Kit and unlock genuine turbo efficiency. Mandrel-bent aluminum tubing reduces turbocharged air pressure loss and dramatically increases airflow from turbo to intercooler, cutting charge temperature and keeping boost pressure where it belongs. The wrinkle red powder coat finishes clean in the engine bay while the integrated port supports water-methanol or nitrous oxide injection systems if you expand the platform later. Easy install with common hand tools and backed by K&N's lifetime warranty.

• Mandrel-Bent Aluminum Tubing: Reduces restriction and turbocharged air pressure loss for genuine flow improvement.
