With all this talk about filters, I haven't seen too many threads on replacement filters. I've yet to take my OEM one out to look at the shape so excuse my assumptions. What does everyone recommend or use for a replacement filter that goes in the stock airbox? I've always been a fan of K&N but I've noticed for the TSX filters from Green & Spoon (I think). Any suggestions?

 

People have suggested the K&N direct replacement filter can provide a slight improvement by itself, and its cleanable / reuseable, so that's nice. Of course I went another direction but if that's not for you I understand. The OEM one on the 2006 really isn't that bad in quality in the first place though.
