When I say best filter these are the requirements I am looking for.

1) easy to maintain so no oiling

2) best filtering capabilities (But i am guessing they are all pretty much on par)

3) longest lasting

4) misc whatever you want to throw in there that you think might help to make an informed decision.

Pretty much the only options you say as far as easy to maintain are clean and oil (K&N), or replace filter (AEM). They all seem to be pretty similar (Injen, Fujita, AEM)

 

i know that for the rsx, since i had one, the HKS CAI filter is the best flowing filter.
i believe its a foam type so i dont know about the maintanance.
but on a dyno video i watched it had +2 more hp than injen. and its smaler..

 

I had the same requirements as you. I sought after the AEM Dryflow filter for my AEM CAI. I got mine for $44.

 

there is no question the fujita filter has the best design... and it features the same technology except it is called superflow rather than dryflow if memory serves me right

the hks mentioned above is "megaflow"... and it is not as easily found as the fujita or aem for under $50
