Just curious to see what the power difference is. I plan on running a airbox with a enormous hole in it with an outerware covering it. And I was thinking on runnin a k&n with an outerware but I am worried about getting debris in my 4000 dollar worth of motor work! SO I may just stick with foam. but I dunno

 

K&N's will flow a bit more than foam but I doubt you'll tell any diffrence.
The K&N's do have a million mile warranty though.

 

they give more power but they dont fillter as well as a foam air filter[img]i/expressions/face-icon-small-frown.gif[/img]
