I measured the sq area of the front of the charge air cooler and used that as a reference for my door vents. I cut 2 holes in the door that were slightly larger than the CAC and then mounted some aluminium grill material to keep from sticking my hands in the belts. I did that before I installed the louvers. Both helped but the rear vents did the most. I now have a 20 degree drop through the radiator now. The back door is running at a vacuum when at speed so between the louvers and the door vents i'm pulling more air through the radiator. The bedroom used to be hotter than the hubs of **** before the mods and now it is not. In the winter it would be nice and warm now it is cold. In the summer it was unbearable.
