I needed an aftermarket intercooler(heat exchanger) as all boosted engines do. I got the ZZP intercooler and it installed pretty good and easy. My Cruze is an eco which means it has that air grille device (where an intercooler belongs) and will throw a code if removed. So here is the instructions for what I did and how I avoided the lost communication with grille code. All you need to do is carefully saw the plastic pieces so that you basically make a 4” version of the part. Using some good tape like electrical tape to hold it together and zip tie it through the hole next to the horns. I’ve attached a picture.
