It's a scoop that sits on top of the engine, that sticks up through the hood, and that's where the air for the engine comes from. Mach 1's come with them from the factory.

As far as what it does:

In all technical aspects, it looks cool and makes unknowing owners think they are getting extra horsepower from "Ram Air" effect, which doesn't work to begin with.

what about those hoods that just have the scoop on the front that has an opening into the engine but doesnt actually connect to the engine through a air intake? does it just blow air on the engine? idk

On the Mach 1, it's connected to the air system, but actually offers no advantage over a standard setup.

There's actually a low pressure area that's created right where the scoop sits at under, let's say, 85mph. The high pressure area in which would actually made a difference is back at the cowl, at the base of the windshield.

Some of the hood vents just get air into the engine compartment to help cool the temperature.

If you bring outside air into the engine and is not directed at a CAI, then, well, you have a dirty engine and no more. Heat vents are another story, they remove heat from the engine, which for some is a benefit.

My first shaker was on a 1979 Trans Am. Non-Functional of course. But at least the fake intake vents were facing the right way (backwards)......:kooky:

thats not a shaker hood scoop, thats just a hole in the hood so the engine would fit under it..

on the Boss 302 the shaker hood scoop actually made a difference. on the 03-04 mach 1 it is almost completely pointless except for looks.

It's almost pointless due to the big hole in the side of the air filter box ....it's more for looks, but you gotta admit.....it looks pretty cool!

02 yellow GT auto......SOLD.
Looking for another, stay tuned!
