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

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.

Cosworth is disposale (you have to buy new one's at regular service intervals).

I think K&N flows more than 10% over OEM.

The K&N and Cosworth both claim around 98% (K&N states 96-99% is what their filters normally test, obviously variance exists).

I understand the literal difference between the two filters. I was wondering more along the lines about those dyno's people have posted with the K&N's.. Could it be assumed that the Cosworth's are going to net the same results?

K&N claims that they enhance flow by 20% or so, based on their panel-filter flow data. Cosworth claims 50% of that. Beyond that...I'm in the dark.
