Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I put about 11k miles on it-is it time or later on? Thanks. Mike

POST 2Original post

depends on the conditions in which u drive. If you live in a dry dusty area, more often. I used to clean mine in my old car every 6 mos. Probabably more than neeeded. Just remember that after you clean it, when you oil it, be very sparing with the oil. Over oiling it will lead to the oil cloggin your mass air sensor. Read the instructions in the cleaning kit carefully. It may be easier and some people just throuw them out after a year and buy a new one, factory pre-oilled.

POST 3Original post

I have KandN's in my BMW 850 CSI. The instruction sheet and the factory service rep say no more often than 50,000 miles. It's pretty easy to just pull the filter and look at it. If you have lots of trapped debris, I'd say clean it. If not, leave it alone. AS

POST 4Original post

Leave it. K&N actually works a little better after it gets some dirt (it helps it trap more dirt). As in the previous post, K&N recommends every 50-100k unless you are using your Porsche for the Baja 1000. Cleaning and oiling degrade the life of your filter. They are only made to be cleaned 10-12 times. Not sure about BMC.
