Thats exactly what was on mine and thats what i did with it. Much happier too, for reasons previously stated. This thread is ancient, folks!

this is no bull crap. of all the things i've done to my 2000 GTP since i bought it in december , taking out the old airbox and putting on a 9 inch spectre cone filter made the most noticeable difference. that includes plugs , wires , every filter, every fluid, 3 inch DP, plog, overkill pcm, O2 sensors , PCV valve , royal purple synthetic... out of all that the air filter change was the only thing that improved my fuel mileage, and gave a noticeable difference in throttle response.all done at different times except plugs and wires so i know what made what difference. got about 1.5 mpg from the filter . sounds crazy huh ?

Not crazy, you just missed the point. Re-read the original post carefully, its about sound not power. I have used a cone filter, too.
