Do hood scoops help cool fuel injected engines?

Answer 1

That depends on your scoop. There are cowl unduction scoops and hoods that help the heat escape toward the windshield using only the wind blowing through your radiator and from under the car. If you use a stick on hood scoop, you would of course have to cut the sheet metal of your hood and treat it to prevent rust, and of course create the duct work that goes to your air intake. This is an aggressive move for minimal gain on horsepower. Subaru's use hood scoops for cooling applications as they place a cooler/radiator under the scoop. Not an air intake.
