I know this seems like an obvious question at first, but then you spend a great deal of time and energy (and some more money) to clean the K&N, and I started wondering. Is the K&N really worth it? K&N says to clean it every 50-100K miles for street use. I would say that mine looked nasty after about 5K, but that is running in the dirt a fair amount too.

I ran a K&N for about 3 months. Once you get as much sand/mud as I had in it, it's not worth trying to clean. I threw the damn thing away.
Buy lots of paper filters.

Ditto on what syko said. K&Ns are great but after a certain amount of mud hits them they never come clean. Plus it seems to me that if they get wet it's like sticking a sock in your intake. They dry out poorly and really bog the motor if they get wet.

I switched back to a paper element and have been much happier.

I've never had serious mud in my filter cause well... I live in the desert. But they do work well in dust, as long as you double oil them.

Please explain. Oil inside & outside? Go over it again on the outside? Knock off the dirt and re-oil?

I would say yes on the street But In the mud/sand I think your wasting your money. I wish I still had the one I threw away. I would show you a pic. I oiled, I washed, you name it but it was so full of $hit it wouldn't draw air very well. I could rub the inside of the filter and sand would fall out. It was like sitting a mud clod on the intake. <IMG SRC="smilies/biggrin.gif" border="0">

Oil em once, let it soak in and tack up (kinda dry) then oil again.

I agree with Syko, I check my filter everytime I change the oil, and with the amount of wheeling I do year round, my K&N was caked with mud every three to five thousand miles. So now I just replace the filter with a paper one every time I change the oil. (expensive, somewhat, but it needs it.) I notice no performance differences. Since I'm running a clean filter most the time. <IMG SRC="smilies/biggrin.gif" border="0">

If you guys are using round filters there is a company called outer wears that makes prefilters.They're made out of a plastic or nylon and can be washed off.Most quads and dunebuggies run them to keep sand out of their filters.

I don't think a K&N protects the engine as well as a regular paper unless you are very diligent about oiling it. It is just much easier to just throw the paper filter away after some wheeling since it will be caked with dirt anyway.

I run a sponge prefilter. It helps some but it your in the mud or sand it's going to get in the engine.

The best solution is to run both. I run the K&N everywhere except the mud. I put the paper filter on when I run the mud. Also, the prefilters work great in filtering out the big clumpy sticky stuff. Makes the K&N last must longer.

Just curious but how did you arive at that number?

Remember, if a filter has more airflow with the same surface area it has to have bigger holes. That means more dirt, even if it is a oiled aircleaner. On that same note I have never compared a K&N to a paper filter as far as number or thickness of pleats. By having more or taller plests you can increase the surface area of the filter element are getting surface area and more flow.

I ran a prefilter for a while to but it seemed that everytime it got wet the motor would hardly run till I took it off. Soaked prefilters and K&Ns IMO starve the motor for air more then a wet paper filter. Paper also dries faster.

I used to run a K&N but it would get way to clumped up too fast and was a pita to get clean after muddin for a weekend.

I switched to an accel foam element and have love the results, i had my engine buried to the intake in water/mud yet when i opened my filter element the inside was perfectly clean. I didn't notice any performance change from k&n to accel, and it is easier to clean and dries faster than a k&n.

I never thought a K+N ws worth it, so I never bought one.. over and over.. then when I bought my ram last may, it had one in there.. heck, it takes WAY too long to clean it.. and because mine had been over oiled, it was leakeing EVERYWHERE, and clogged my spark plugs. I think they are too much of a hastle for what they are... Kinda dumb, figuring my drop in filter is like $42, and the paper one is between $3-7. come awn, for those prices, and knowing how cheap I am, what do you think i am gonna do next time I have to clean them?? yeah... thats right.. PAPER
