Laino is not far from the truth.

The K&N oiled cotton gauze filter is a poor performer. Restriction levels are high when loading occurs and it's quite poor at filtration. Nothing to gain but quite a bit to lose. Marketing or performance? Think carefully and evaluate other options.

 

if anyone cares, I put in the k&n drop in, it rly only makes a noise difference at 1-3k rpms where it has a very minor hum as it sucks in the air. pretty undesireable imo, nothing while stomping it.

I miss the amazing noise my aem v2 made in my accord.. that was a night and day difference!
