    How often do you clean your K&N air filter?

    K&N recommends a cleaning interval as long as 50K miles … that seems a bit too long. Any advice on cleaning and oiling the instructions do not mention?

    50k is a bit long. But you don't want to do it too often. They actually filter a bit better when dirty but don't lose much flow. I'd say every 10 - 15k

    I agree with GV. You should check you filter every oil change, if you have been driving in severely dusty conditions you could choke it in just 1 - 2000 miles. Every 10k sounds about right to me, but check it often to be sure. K&N filters are cotton, if dirt creates a hole in the filter due to lack of maintence, then it basically wont work and will allow dust and dirt into your intake....

    I noticed a significant (but not a lot) amount of dirt after 8K. I cleaned my filter and lightly oiled it anyway. I'll wait another 10K before doing it again. Always a good idea to check it once in awhile though.
