Until I buy my Needswings Dual CAI's..........I am putting new air filters in my NA Coupe. I'm just turning 20K miles on the car and was reading this car will breath much better with these than the OEM's. I'm not even sure the OEMs need replacing but I would expect after 20K miles I ought to make the switch.

I was reading the K and N filters are higher air flow and this simple replacement actually has a noticeable difference in throttle response. What are others experience with this simple switch? Also, do others have suggestions for better / higher flow filters (that still protect the intake)?

Thanks.
