Introduction

In this installation guide we have provided step by step instructions to remove the OEM Intercooler, setup, and install the 27WON Performance Intercooler.

Advisory:

  • Working under the vehicle requires a safe and sturdy location for the vehicle to sit on jackstands.
  • The engine bay will be hot after recent vehicle operation. Allow the vehicle to cool or use a fan to cool the engine bay before working on the vehicle.
  • Removing the bumper is very difficult to do by yourself and can result in scratches to the paint or headlights. We strongly encourage using a friend's help during bumper removal and installation.
  • Trimming the rubber OEM intercooler shrouds is necessary for 27WON Intercooler fitment. This is easy and can be done with scissors.
