Well I currently have an aem short ram but ill be getting rid of it very soon, im replacing it with an icebox. I decided that the comptech foam filter would be to high maintenece as I would have to clean it more often (60bux for a foam filter didnt spike my interest either). People have said that K&N would be the next best choice. But I was looking on their site and came up with the results

1998 ACURA Integra AUTO 1.8L L4 F/I E-2427 Air Filter All
1998 ACURA Integra AUTO 1.8L L4 F/I 57-3509 FIPK GS-R
1998 ACURA Integra AUTO 1.8L L4 F/I 69-0003TB Typhoon Kit GS-R

Initially I was looking to get the E-2427 model but what are the other 2 options?
what should I expect to pay for this filter.

 

you can't go wrong with a K&N filter

 

i have a apexi filter that i bought off groupbuy for $65 and it works

 

Any decent K&N with a velocity stack will do the job.

 

k&n "velocity stack"?

 

Velocity stack is a smooth opening at the entrance to the intake piping. That way no air has to do a 90 degree turn to enter the piping causing it to be highly turbulent.
