picked up consistent 2mph trap with free airbox mod! This is a great, cheap mod without a doubt. All I did was remove the top portion of the airbox and tie-wrapped down a k&n panel filter (don't really think the k&n makes a difference, I'm sure the paper filter would be just as effective).
I had been to HRP on sunday (5-19) and made four runs. Weather was 72, dewpoint 58, 55% humidity. I trapped 113.4, 114.0, 112.9, and 112.2. The car was bonestock (besides a shifter and TR55 plugs).
I went yesterday and picked up a k&n and some tie-wraps. Installed the filter, ditched the top portion of the box and that was it. Only change to car.
Went back to HRP tonight (3-22) and made three runs. weather was 76, dewpoint 66, humidity 70%. I trapped 115.67, 115.50, and buzzed rev limiter in 3rd gear on the last run and trapped 112.9.
This is a GREAT, CHEAP mod!! The car pulled NOTICEABLY harder and the trap speeds confirmed it. Even the 1/8 mile traps were up almost 1-1.5mph from Sundays runs (which, btw, where in slightly better weather).
I recommend this to anyone wanting more performance from the intake dept, but who are not willing to shell-out $500 bones like all of these intake products are demanding!!

Re: picked up consistent 2mph trap with free airbox mod! A local guy with a Z06 did the exact same thing to his. He seemed quite happy with it as well.
BTW, does anybody have a pic of a stock C5 airbox? How different are they from Z06 air boxes?

Re: picked up consistent 2mph trap with free airbox mod! The stock 2001 C5 airbox is the same as the 2001 Z06. It has a small opening cut into the top but is larger than prior C5's. The '02 Z06 box has an even larger cut out section. Replaced the top in my 2001 C5 with an '02 Z06.
