What is a ram-air hood?
A ram-air hood is type of hood designed to “ram” more air into the engine bay. This is done by the hood’s design, featuring a slit in it allowing more air to enter the engine bay. Ram-air hoods increase performance of the Cold Air Intake system, by putting more air into the engine bay. Though this statement’s accuracy depends on what type of CAI system is installed on your Pontiac Grand Am. There are two types of ram-air hoods available for the Pontiac Grand Am, including the notorious SC/T hood, and the SD hood.
