best intake......
I was told by a trusted freind that I would pick up a few by going to a box and lid.
IS THIS TRUE. Any real proof out there????

Assume on a scale of 1 to 10, a stock engine requires 5 and a heavily modified one 7.
If an aftermarket lid can flow 8 and a volant/FIPK 9 you'd see no differance because it's beyond the requirement of the engine.
Air box resonance and cool air ducts combined with surface area are often far more important than the flow ability of the filter eliment, hence people who use k&N drop in filters see no performance gain.
In addition OEM paper filters have been bench tested to flow well enough to support 500bhp n/a.
on any firebird i would go volant as it has openings to make the volant worthwhile.
click on my sig pic for more pics of the hood and intake setup
I switched to a K&N FIPK because I thought the same thing you did. I consistently ran about 106-107 in the quarter.
However, I made more horsepower on the DynoJet with the K&N setup. With the lid and filter made 318 rwhp, with the K&N FIPK, made 326 rwhp, K&N and MACs, made 340 rwhp. The hood was open for the dyno runs. No computer tuning for any runs.
These are not everyone's results...just mine.

but i did a back to back dyno test. 5 minutes apart. first with the volant, then with the lid (lid, filter, lower air box, everything) and we picked up 6 rwhp with not touching anything else.......
however the TA version on the volant flows MUCH better do to the neck. and i seriously doubt has the same flow problems as the camaro volant. (do a search ive posted up pics and write up on this problem)

i dont believe this to be true, yeah it might not be a big gain with a k&n versus paper but there is a 1-3 hp difference depending on which dyno you want to look at, it all adds up...a stock filter will be more restrictive than a k&n it is proven...
