Yes but they also give wondefully screwed up UOSA's with lots of SI (dirt). Every engine loves that...

Maybe it's just a K&N issue (cheaper quality) but with my S&B filter my silicon levels (when they didn't get spiked because of a sandblasted intake manifold) were well within universal average.

Yes, K+Ns are louder.
But not exclusively from simply having more holes than paper.

Inside the stock airbox, it makes no difference what filter is in there. Paper, K&N, foam, no filter... the intake resonance volume is controlled by all the baffles/chambers built into the stock system. Only when you remove the box and replace it with an open element cone filter and/or associated piping will the intake tone become much more audible.

Any perceived noise you hear from a drop-in K&N is just a placebo effect... it's not flowing that much more.


the air charge is normally silenced by a stock intake tubing's strange shapes. the filter has no effect on it. I would purchase a good dry filter. I ran k&n's but recently ditched them on both vehicles. Mileage has not suffered at all and i feel better about it after reading hi Si UOA's from other people.
