The stock setup really is a cold air intake and a lot better than people think; certainly better than the systems that hang a couple of filters in the engine bay. As another exercise I have tapped a hole either side of the one of the filters to measure the pressure drop (if any) across it.
Hey woody, what where the numbers on your pressure drop test at full throttle?
I figure the air box is good enough for the cars performance output, but I did remove the holsters where the two plastic air intake tubes slide into the grill, they where the most restricted part of the entire intake system! Don't believe me check it out, you'll see.
I'll post pictures later, I'm sure I'll get dumped on by some of you guys for removing parts from my car, but oh well, hahaha.
