I was hoping someone can tell me how to ID a factory ram air hood from a reproduction? Is the GM part # on the hood, and if so, where would it be located? Is there any other way to authenticate the real thing? Thanks!

not really sure if there is a way to id it. i do know that the factory ramair hoods are heavier than the after market ones. my friend has a aftermarket one and his hood is a lot lighter than mine.

The underside of them all look different, the GM one has two pretty distinct X's of supports and no way of routing air over the air box.

There are some aftermarket hoods that aren't designed for more style / "performance" (with the cutout over the airbox)

They are usually made of a different material than fiberglass if they are just a standard replacement that a body shop would use for an insurance repair, They are made of "SMC" plastic. Article: http://www.autofieldguide.com/articles/020305.html

Another good way to tell if they are GM or not is if there are holes to cover up the nostrils. I don't think the aftermarket hoods have those holes drilled.

Found an old picture of mine with the car. You will see it has the factory padding. In '02 and I believe '03 the back plate behind the ram air had a blocker plate that could be removed with an allen wrench. I think '04-'05 cars had it epoxy that kept it closed. The underside structure of the factory hood does make an X shape. There is no duct work or anything leading to the air box. If its on a car that is '99-early '02 then it is not standard in any way. Most likely aftermarket. Just some food for though. Should have the padding under the hood. Though I removed mine.

Unfortunately, it is not on a car. One reason I don't know if it is real. It appears to be "white" underneath the paint (through a scratch) - though don't know if that is the primer.

The holes for the hood mounts are metal sleeved. It does have reenforced ribbing underneath, like a factory style hood.

Good point about the padding. It doesn't have any, but I don't know if it was stripped off and repainted, though.

When you are talking about "plate", are you talking about the scoop opennings? I didn't there there were block offs since the scoops inserts were bolt ons? Or is that your point, the scoop inserts on the aftermarket hoods were molded into the hood? Thanks!
