Bought a used truck with a K & M air filter.
Is it worth the time and hassle cleaning one out?
Is their cleaning kit a necessity, or can you just wash it.......buddy said I needed the kit for the oil or something.?
....... TIA ................................Mark

I have one in my duramax. I rarely clean it as I prefer it to have more junk on it so it filters better. If you are in really dusty area, I would consider going back to oem

Personally I would change it out to OEM filter. Lets too much dirt in.

Wash it out with soapy water.... air dry..... reapply the recommended oil and put it back in.
But... How dirty is it that you feel it needs attention?
Only one I run is on my Harley. It hardly needs any attention running up just a half mile of shale road before blacktop.
I've been told they can become quite dirty before needing cleaned and still work efficiently. Really.. the entire idea behind the k and N is to allow more air flow into the engine. If you truck is not going to be used for high performance in any time Id say go with the other guys thoughts of just a good ole paper filter from stock. Less mess and time involved to clean because those you chuck and replace with a new one.
I guess though I'm not real sure why some guys can't trust a k&N filter... Back in the days of the oil bath... it's the same theory pretty much.

I have a k&n style filter on my truck..different brand name same idea. My dodge had a terrible filter set up on it to start--you had to stand on your head in the engine compartment to check the filter. I dont think it helps hp or mileage that much. It is easier to check and change though, and if i can find a paper filter that fits, i think im going to go back to it.

I put one on my Dakota years ago. I got about 1/4 mpg better with it over the stock paper filter. I don't think I would run one if I drove in dusty conditions.

I recently bought an older pickup that had one. First tank I got 20 mpg. After cleaning the filter I got 21.5 mpg. It was pretty dirty. I bought the kit at autozone--a can of spray cleaner and a can of spray oil. I was a bit skeptical at first. But I followed the directions and it worked great. I did prop it up in front of a fan in the shop so it dried quicker. IIRC the kit was 12 bucks. Enough for at least 4 cleanings if not more. If I can find it next time.  After using the k&n cleaner I don't think I would mess with soap and water. It was quick and easy. www.knfilters.com/cleaning.htm |

Like Kevin said, I'd use the K&N kit. Real simple to use and you know it'll be right. I've got them on the Harley's and my truck. I think the truck one is supposed to run 50,000 miles before needing cleaning. I probably cleaned it a little more often than that, but that's still cheaper than an OEM one since you've already got the K&N. Only takes a little bit for them to dry after cleaning and then you can re-oil. I do them in the evening, then they're real dry by morning for the oil
