These are just over the headers, so they will also vent heat out of the engine compartment at the same time.I dont really care for them....but the fairly small quantity of them would not offend me. Do they help relieve the air pressure under the hood, or would you need more for that to be of any value?
The idea isn't new, the 68 Shelby GT cars with AC, they had grills on each side of the rear of the hood to release hot air. The 63 Falcon built on Gas money had a cool idea they put panels with holes dimple died on each side of the hood that looked great.OK sports fans, a question for all of you and be honest. I'm not thin skinned, (unless you talk about my wife) so tell me your opinion of the hood louvers?
