Header, Intake, & Exhaust - Air Filters

I have an Injen short ram intake on my 94 civic DX.I changed the air filter about three months ago, and the car felt so much different. I feel that I gained a significant amount of power, but now it seems like it is back to how it was. What kind of air filter would you all reccomend to get the most gains to make the car breathe better?

you are probably feeling a placebo, cleaning it probably did help, but i doubt you felt the difference. get a aem dryflow, and call it a day

K&N and AEM Dryflow are the 2 your gonna get hear the most about, and thats for a reason. They're both real good :)

AEM Dryflow FTW[sm=groupwave.gif]

filter's won't make noticeable difference in HP, not even +1HP. however, in the long run, the brand names last longer AND they help keep your engine clean - the MOST IMPORTANT aspect of a filter. a cleaner engine means a longer life for it.
