I'm considering the Ram Air Mod shown on You Tube for my 2002 Camaro SS, where you remove the stock air filter, draw lines below the opening of the bracket onto the lower mounting bracket, then cut out the flat material that blocks air from entering from below the air filter. Has anyone tried this mod, because there was mention of a whistling noise at some speeds, which I'm concerned about, and/or how to prevent the noise while reaping the benefit of the hugely increased airflow. Please Help if you can OK. Thanks !

I did that mod on my 99 Z28. Don't know if it ever helped? Never noticed any noises afterwards. It does dirty up the filter though.

All 98-02 SS cars already have "Ram-Air" whether you believe it functions well or not. On the SS cars, there is an opening at the front of the air box at the bottom where the ducts from the hood scoop route the air. The bottom flat part of the airbox, in a way, directs the forced air from the hood (read: My best guess, is it doesn't force any air below 60mph), through the filter to the MAF.

I have seen this mod on the forums, etc, and it's not one I will be doing to my Heads/Cam/Intake/Exhaust 1999 SS. I would put money on it not being worth even a couple horsepower except maybe on Z28 cars that allowed no air incoming from the hood.

Only worth it if you keep going lower and install a CAI. Those cars breathe from beneath the car, which is why there's that plastic air deflector under the front end. It pushes air up into the engine bay; the CAI provides a duct from that deflector straight up into the air box and seals it.

I did it on my 2002 Z28 and for the few hp you gain it wasn't worth it for the amount of mud and junk you got in the filter. It is a useful performance mod, but I don't think it's worth the hassles and muddy filters.
