IC100028 APR 2.9T Air to Water Intercooler

Notes:
These instructions were written for a North American specification Audi RS5, but other models are similar.
When disassembling the car, be sure to keep all fasteners so they can be reused. It is recommend that you get some kind of compartmented tray to organize the fasteners, such as a fishing tackle box or several large ice cube trays. Fasteners that are not reused for reinstallation are noted in the instructions. All directions used in this manual (right, left, front, etc.) are based on if you were sitting in the drivers seat of the car.
These instructions assume that you have basic mechanical skills and several varieties of basic hand tools in order to install the kit. If you have any questions about the install, feel free to contact your APR representative.

1. Support the vehicle on a lift, and remove the two front wheels.

2. Remove the engine hood latch by pressing in on the button on the back side of the latch, and then lifting the latch up and away from the car. Be sure not to close the hood at any time without first reinstalling the latch!

3. Remove the six push pin style connectors holding the cover between the front bumper and the radiator support. Carefully pry the  raised center part of the pin up, and then remove the entire pin assembly up and out of the cover.

4. Carefully lift up on the front side of the cover where it attached to the grille. Then, pull the cover forward and away from the core support to remove the cover from the car.

5. Remove the four T30 screws holding the top of the bumper cover to the upper bumper support.

6. Ensure the ignition is off on the car. Disconnect the cable to the front distance sensor, then separate the harness from the upper bumper support. Do not turn the ignition back on in the car until this has been reconnected, or the car may require having the driver assistance system recalibrated!

7. Remove all the fasteners from the front side of the wheel well liner. Typically, this is ten T25 fasteners, two 10mm nuts, and one T30 screw. Repeat this step on both sides of the car.

8. Carefully separate the front wheel well liners and fold the liner back behind the brakes so they are out of the way.

9. Remove the T30 screws holding the bumper cover to the front side of the fender. Also remove the push pin style connector between the side of the bumper cover and the bottom of the front fender. Repeat on the other side of the car.
