I have an air foil for sale...I bought it off of here from someone and I'm not going to use it because I went to a BBK 52mm Throttle Body and it doesn't fit it. Also, he said it came off a 94 Z28. I never installed it on mine when I got it. I think these air foils are supposed to come with a nut that drops down inside the TB to hold the bolt in place, but he never sent it. This is why I never put it on, mainly cause I was too lazy to go to Lowe's or Home Depot and pick it up. Anyways, it's the air foil and the bolt that comes with it. If it requires a nut, you can just pick one up for less than a $1 at any hardware type store. Asking $25.

 

Anyone?
