Tow hook maybe? At least that's what it is on a lot of other makes (Bimmers, Scions, etc.). Not sor sure though...I don't have one.
Dunno good question. Only one way to find out. Take the front bumper off and investigate. LOL And quick question back at you. Are you turbo or is that just one big and very clean radiator?
A friend of mine, when he wrecked his tC, I saw in a picture that he had the same thing. But, the little circle was popped out, I couldn't tell what it was for though. Didn't look very amazing though, not like a tow hook or anything, but I have no idea.
Thanks Sine! I was afraid to pop it off to look in fear I'd scratch it up or break a tab and be stuck with a hole in my bumper! And No Jog, no Turbo (yet) It's just a clean radiator.
