Okay so here's the story. Back in August the RSX was totalled, collision off front end, killed the radiator, fan, front bumper and a little bit of the frame. Insurance totals it. I had some mods done to the car, notably an AEM CAI. I buy the car back from insurance only to notice that the filter from the intake is missing. Great In about a week some friends of mine and I are going to be transferring the K20A2 to my Civic and I'm trying to use the AEM intake in the process. Do you guys know what the part # is that is a suitable replacement filter for the filter that AEM gives you?

 

So you want a different filter or you want another K&N filter??

Get another K&N, im sure you know its worth it.

 

you should be able to go to any parts store and get one or order one from them. u mite also look into a green filter company they make some nice ones also

 

K&N has an online catalog of their diffente filters, even the cones and cylinders, etc. measure the diameter of the end of your intake pipe, figure out how long you need it to be and look up a filter that fits your bill. i usually copy and paste teh part number off the site, then go look it up on summit, jegs, autozone, or froogle search it for prices.

here the link to the K&N universal filter catalog

 

most cold air filters(from k&n) are differant than short ram. go to your local performace shop and order one. or you could try advance auto they also sell filters. but the cold air has a 4 inch neck as apossed to the short rams 1 inch neck. I bought one for my prelude and It took me 3 weeks before I got the right filter. so good luck
