Air Filters

This probably wont be to long of a thread but ive been reading about how some people think that the oiled air filters could and are getting the MAF and other things dirty and oily and they are not reading as good. Imo this somewhat makes since to me, but there are alot of variables to look at how much oil, what kind of oil, what brand oil and filter. But i was wondering what everyone thinks plus. My question is i have a K&N filter that you are supposed to oil each time you clean it. Will it let to much dirt through if I dont oil it or if I just run it dry like its a paper filter??

 

Each brand oiled filter (like K&N, Amsoil, etc) uses their own special oil. You can't use anything else but the oil they require.

YES - you MUST oil it each time you clean it. The oil is what filters the finer particles. NEVER run the K&N filter without oiling it.

I've had K&N drop-in filters for years and never had any problems. You should clean it regularly, even if it looks OK. I cleaned mine every 6 months. Use a stock paper filter to put in your truck overnight while the K&N filter dries completely after you clean it. Don't oil it unless it's completely dry. Read & follow the instructions on how to clean and oil it. Don't over oil it.

K&N filters cause much heated debates. Some folks hate 'em while others like 'em. I had them on many vehicles for many years.

However - there is another high-flow air filter on the market that doesn't use oil. It's called the AFE Dryflo filter. I've got one in my tacoma. I decided to give this a try and see if I like it better than the K&N.
