The quick 8, is it 1/8 or 1/4. I prefer the 1/4 but we had and issue of turbulence in the grill area at 170+ that tried to suck the hood off of the car and wound up cracking the scoop and did some damage to sheet metal under the hood. 10 fastners holding the hood down even at the front corners of the hood. Looks like ill have to put a couple of more across the front as well. We have a an air filter pan for the car that seals the scoop off from the engine compartment so the car only gets fresh air fron the windshield area and it even appeared to have sucked the back of the hood up as well.
