Funny you should bring this up, as I've been bouncing this around myself. I'm beginning to wonder about the K&N now. I'm getting conflicting info on it from two sources. For example, here is an email I got from K&N:
quote:
Hi Patrick,
Our anti-drain back valves are made of Buna N (Nitrile) 60 Durometer. The
oil filters contain no fiberglass.
Hope this helps.
Thank you,
Lisa Sutton

But earlier in the week I got this email from Champion Labs, who makes the K&N:
quote:
The K & N oil filters contain a cellulose media impregnated with a
percentage of fiberglass and polyester fibers. This media is designed to
be used on race applications, however it meets or exceeds all original
equipment requirements for fit and function for regular applications as
well.
The anti drain-back valve is made of nitrile rubber.
Thank you.

So does it contain fiberglass or not?
But yet the Wix filters contain glass media, plus a better silicone antidrainback. Read this (Wix is the premium filter listed, value is their off brand stuff)

I was also told from a Dana rep that these filters will not go into bypass mode unless the oil is cold, that's how good they flow.
I'm using the K&N, but they are more expensive and look to be phased out up here too. I think I might just go straight to the Wix filters even without using up my last K&N that I have for each of my cars, this way all my oil testing from now on is with the same filter, for more consistency.
