The K&N that came in my car doesn't seem to hold it's oil. I'll clean it, oil it and in a month it looses it red color like all the oil is gone. The K&N's I have in my other car keep their red tint no matter how dirty they get. I'm worried it's not filtering correctly anymore. Any body have a similiar experience?

never heard of a k&n going bad

turn it back into them... they have a 1 Million mile warranty

I looked into it, you need a receipt. Don't have one.

I emailed K&N yesterday, to see what they say.

if you bought it new from advance or autozone, they keep electronic copies of all transactions, they can print one for you.... if not I'll pm you with what to do.

you have a pm

I didn't buy it, Darryl put it on the car when he owned it...that would be 2 owners ago.

The guy I bought it of off works with us and I know him pretty well. I also know he didn't do anything to the car when he owned it. I pretty positive he never cleaned/oiled the filter when he had it. I wonder if the neglect just killed the filter...

if they won't take it back without a receipt,just go buy a new one and hold on to the receipt for awhile and return it in a few months or so

funny how people always have the same idea that I do

I just said the same thing in a pm to him yesterday

it works with just about anything, I love that little trick

how often should one re-vive thier K&N? i've had mine on for a little over 2years now.

and how would one go about doing that?

I K&N recommends every 50k. I usually clean mine about 3 times a year, 15-20k a year. I live out in the country and get a lot of dirt and bugs.

See here for instructions: http://www.knfilters.com/clningins.htm

You by a Recharger kit which contains a spray cleaner and the proper oil to spray on the filter. Spray the cleaner on, let sit for 10min and rinse the filter out with a hose. Let it dry in the sun, spray the oil on the filter until it doesn't show any white spots. Pretty easy.

sweet ..thanks
