Not just stuck on though. If they were professional molded and holes cut in the hood under them, they would look pretty good and be functional. Would they allow enough air to enter the engine bay though or hardly anything at all?

Well.....eh....uh.....umph.....



Yeah, none of the above. Just my .02. IMO it work like sh*t and look like ass. But, I could be wrong with the right body work I suppose. I know the evo hoods are super rare to find. I would do a more simple scoop if it were me. Keep an eye on eBay and craigslist maybe for a real hood?

You could buy the GTR style hood vents and have them molded in.

Just sticking them on will look tacky and as if you went to Pep Boys. lol Mold, paint, and look good!

Really, you should do what you want. people will hate no matter what you do, so do what you like to your own car.

Get a functional NACA duct if you're going to the trouble of getting them molded.

A decent NACA duct can be cheap, around $10-15 for vac-molded acrylic or fiberglass

May guess the vents are to small to allow air to help cool down the engine. Not worth it at all.

GTR style hood vents would definitely look better.
