Plastic intake parts...how do they work?

So I got these plastic pieces with the car when I bought it, and I've decided it's time to put them on. I have no idea what they're called and tried searching, but I found nothing. Hopefully someone will at least know how and where they bolt up to. Name:  P1010750.jpg

Re: Plastic intake parts...how do they work?

The big one on the left goes in front of the radiator at sort of an angle. It separates warm air between it and the rad (coming up from underneath), from cool air coming in from the front. The right edge of it in the pic is the top and goes right above the rad. The left edge is the bottom and goes about 8" in front of the A/C condenser at the bottom. Slips up under it if memory serves.

The 2 small pieces hook to the air filter boxes.

The large piece in the middle goes over the top. The 4 bolt holes at the right of it line up with the 4 bolt holes across the right edge of the left piece. Those are the bolts that hold the radiator clamp (plastic piece) in. The left edge of that would go to the rear edge of the bumper cover.

Re: Plastic intake parts...how do they work?

so i just replaced my front end on my camaro and that is not how those were hooked up on my car (at least from what i'm reading). The part on the left gets hooked up in front of the radiator with the holes facing out the two holes in the bumper. the two plastic pieces get hooked up from the bumper through the two holes in the piece in front of the radiator. The plastic piece in the middle is for between the bumper and the front plastics under the car. I'm not really sure the reason for the middle piece of plastic, but i would think that it Keeps the air down until it reaches the open spot between the radiator and the bumper. Those parts are from a TBI Camaro and not a TPI as sofakingdom is probably thinking. The TBI camaro had the air intake off to the side, and the TPI had the double snorkel in the middle. So those plastics are not included in the TPI version of the car. In my opinion though those pieces are not really all that important for air flow though. The biggest thing that you want to make sure is still good is the air dam under the radiator. If that's good then those pieces are more cosmetic than anything.
