(Noun.) An interfooler is a device commonly fitted behind the front bumper or grille of a vehicle to closely resemble an actual front-mount air to air intercooler found on most modified turbocharged and some supercharged vehicles. It causes enthusiasts to think that a car is turbocharged, but it really is not. (a.k.a. Baller on a budget.)
Is that an intercooler? No...it's a "front mount air intake system". Interfooler!
"Why did you strip the paint off your A/C condenser?"
"I did it because it looks like an intercooler now..."
If you see a car at a car show with a front mount intercooler, but the owner refuses to pop the hood, it's probably not really boosting.
