APR CI100054 MQB Compact Open Intake Installation Guide

Notes:

These instructions were written for a European specification Polo GTI, but other models like the Audi A1 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.

If equipped, reconnect the electrical connector to the MAF sensor. Be sure to slide the white tab on the connector forward to lock the connector in place.
Reinstall the factory air box inlet, securing it with the two original T25 screws.
Reattach the coolant hose into the two clips on top of the factory air box inlet. Connect the factory vacuum line that went to the side of the factory air box onto the straight barb fitting on the side of the APR air box.
Connect the two metal clips on the front of the APR heat shield to the bottom of the factory air box inlet.
