K&N filters...yay or nay? (from a filtration standpoint)

ImportConvert · 02-29-2012, 02:31 PM

Just curious if anyone wants to weigh in here who has actual physical evidence for or against their use, regarding premature wear/lack of filtration, or not.

these are the filters i run from Cosworth. check the specs:

Reduced restriction (10%+ compared to OE filters)
Over 98% efficiency (*ISO5011:200 Fine Dust Test)

Performance Air Filter - Performance Air Filter - Cosworth USA

I just ordered one of the Cosworth filters for my S2k.

Nick911sc · 02-29-2012, 03:03 PM

So what's the difference between the Cosworth's and K&N's?

dmatt · 02-29-2012, 03:11 PM

I use Cosworth's as well; it requires no oiling.

Pretty sure K&N doesn't make a dry filter?

if i'm not mistaken, K&N's are oiled out of the box. they may not "require" oiling, however, that's how the filter traps dirt and dust. no oil on the K&N = no filtration, from my understanding.

Exactly. After it gets dirtied the filter must be cleaned, dried, and re-oiled.
