I did the same, with the Spectre filter.
Worked great until I started experiencing the heat lock and poor acceleration.
Sorry to everyone who disagree but, I picked up an Ebay CARB exempt 2.5" CAI and replaced the wire mesh cone filter it came with, for a K&N cone, had to use the handy spacers that came with the Spectre.
Noticed a great improvement through the bar but best at higher RPM. vs. the SRI seemed better at lower RPM. It tucks in pretty solid above the splash guard and in front of the wheel well. 01 SE.
