Sorry, gonna have to call BS on the lasting nearly forever. Maybe physically, but I really can't expect any filter to retain 100% effectiveness after 100,000 miles, if that's what you ment.Black B15 wrote:I am running the K&N panel filter in my car as well, no issues or problems. The biggest problem most people have is severely OVER oiling the filter and the MAF sensor doesn't like that so much.
If you maintain it correctly, meaning cleaned and oiled properly, a cotton media filter like K&N will last damn near forever.
It is easily worth the $50 or so. You can get a "recharge" kit which is a can of filter oil and a can of cleaning agent for around $20 or so and like ImStricken said that will last you quite a long time.
I don't know if the implication is intended, but the impression I'm getting from the K&N fanbois is that with regular cleaning/oiling, these filters will perform like new no matter how many times they're resued. Seriously?
