yep stock ones pop right out and functional ones slide right in to replace. Probably easiest mod to do.

The originals probably didn't ram much air either. The "functional" hood inserts look better than the solid plastic pieces.

Speaking of "ram air", I wonder how much more air you can get from the Cuda II hood over the stock hood, and if it would have a more beneficial "ram" effect.

I hate saying Ram Air, it's just too..... Pontiac. God rest its soul.

do a search, someone on here did a test about 18 months ago and with the functional scoops the engine bay temps dropped around 20 degrees when moving.

every little bit helps especially if you are running an HAI kit

Aguy in our club installed a Cervini ram air system to his hood and they work just like they are suppose to.

Dave, they do work but not as they are supposed to. There is a negative air pressure that develops over the scoops. Some NASCAR wind tunnel tests verified this and the videos are posted in several areas on Forum.

The Cervani system is actually useful, but not as intended. The system creates a flow of cool air from the bottom area of the intake and out the hood vents. It actually works in reverse, quite likely unintended, but certainly useful for cool air.

There is likely a much greater advantage to the cool air.

One "wants" to believe that these vents force air in. They don't. They draw air out. You need to get at the height of a functional TA hood or shaker system to get the upper air in and the big advantage is a ready supply of cool air.

The functional vents are useful and it seems the Cervani system too, only not as intended, but possibly of a greater reverse function value.

So when is someone with the Cervani system going to put an emblem next to their now "functional" scoops that says, "SUCK AIR" ?
This I can buy into. It certainly is not the way one may intend, but heck if it still helps..... well then that's what car guys do.

So if the hood scoops just vent hot air then the reverse pressure will keep all the oregon rain out if opened up?

Yeah that was my thinking, but it does look cool but like the GTO, 67-69 Firebird and a whole host of others GS STAGE 1, unless it is way off the hood or has a NACA duct ala AAR Cuda or is right at the cowl facing backwards um not going to work, or work in reverse. Most of those vents one sees on like an EVO, work in conjunction with a NACA duct belly pan and air is being forced out of the hood. STI went the other way by popping up bigger and uglier hood scoops but these only work at speed and during normal driving, autoX etc the air is getting heated by the exhaust and engine and then HEATING the intercooler...:notallthere:

I've seen the T/A scoop in real life a DWB, and I tried to like it, but it is too modern, too fat, too low, too round, too something it is um just ugly.

I'm not even going to muse how functional the shacker hoods are....
