Just got new NA K&N Filters for about $33 each at Advanced Auto. I bought a few other things and got free shipping. They came in 1 day

Install is easy. My filters were original OEM and were dirty but not horrible (19K miles). The OEM are definately thinker, have more layers etc. so I'm sure they are more restrictive than the higher flow K&N. However, the K&N are very thin and I wonder if their filtration effectiveness is anywhere near as good. I know people say they are the best, and I'm sure they are, but just wonder have they can filter the "fine" particales as well. Oh well, they're done now and I hope the addition as toe the driving response.
