INSTALLATION GUIDE
1. Remove ECU and have APR inscription module and software installed.
2. Drain coolant and oil.
3. Remove air box and battery to gain better access to components during installation.
4. In order to gain better access to the area behind the motor, remove the front axles and pendulum

the turbo and it’s associated plumbing.

valve, and diverter valve to be reused later.
6. Remove turbo exit plumbing including the pipe crossing over the engine. Remember to set aside the
bridge clamps to be reused later.
