Purolator isnt really that good; FRam is the better choice for quality. But whatever you use is cool I guess, its just a filter. I use OE Honda myself.

Also, does anyone else use RSX filters on their DOHC motors? I heard you get less fluctuation during VTEC by doing this; but I didnt know I had much fluctuation during VTEC? Just something I heard and wanted to get some opnions.
