It's under the front bumper cover on a 94 z28. It looks like a a piece goes in (possibly a flat black plastic piece) as there's bolt holes on the bottom of the front bumper cover I believe. Looks like it might cover up the rad and the windshield wiper fluid. Anybody know if this piece exists, or what I might be talking about?

 

Do you mean the air dam, that sticks down a few inches and forces air up into the front of the radiator?

 

Or possibly the air baffles farther up in?



Number 1 and 2 in the picture are the baffles that actually go up in front of the radiator between it and the washer resevoir, etc. The bolt together in the middle. Number 7 goes down on the bottom and is the air dam Injuneer was talking about.

Number 8 goes on the front corners under the bumper cover and bolt to your inner fender wells. 5 Goes on each side of the radiator.
