Put a K&N in my wife's TJ a year ago and have only washed and re-oiled it once. One question about reoiling...are you supposed to use a cloth to re-oil or are you supposed to spray it on or some other method? Just curious as I applied the oil with a cloth on the intake side of the filter.
You have to take the filter out completely. Spray the oil (as per the instructions) directly onto the filter and the oil WICKS into the paper material.
The one thing I did ....I had a spare paper filter that I'd put in the vehicle while I was cleaning the K&N. I let the K&N sit overnight to dry completely before re-oiling it. If the filter is wet when you re-oil it, the oil can't WICK into the paper and it won't filter properly.
