Okay. I know we discussed cleaning air filters last year but mind is leaking info faster than I can store it ! ;D
I can clean the filters with just soap and water, correct? Then after it's dry I oil it with what and how much?
Thanks folks!

Terry, I don't know if soap and water works. But K&N (the filter company) sells a "cleaning kit" which comes with two bottles. One is a cleaner and the other is the red oil you put on after it is clean. I like to moisten the filter with the red oil until it looks ALMOST all light red in color. Don't over do it. Then I let it spread/drain/drip off over night before I put it on the carb.
I hope this helps. Others may have different/better ideas.

Dish soap and water is all you need. The other stuff just lines the pockets of the K&N executives.
There is a distinct procedure to doing it correctly, this is what I do:
1) Stand your filter on the closed end in a pan or bucket.
2) Pour about a gallon or so of hot tapwater (so actually lukewarm) into a pitcher. Add a teaspoon of dish soap (any brand).
3) Pour the soapy water inside the filter , until you cover the filter 3/4 of way up the pleated material.
4) Cover the open end of the filter with your hand and slosh vigourously.
5) Pull the filter out of the now dirty water, and rinse in the sink. Clean water always goes on the inside.
6) Let dry.
7) Re-oil with a quality filter oil (I also recommend K&N).
A few rules of thumb:
A) NEVER allow any of the dirty water to get inside the filter by laying it sideways in the pan or bucket, or completely covering it with the soapy water. The inside of the filter should only ever have clean water in it.
B) DO NOT blow dry your air filter with compressed air, it will create unseen damage.
C) Same is true for using pressurised water. Water direct from a faucet or hose is OK, but not from a spray nozzle or gun on a hose for the same reason as B) above.

I bet Brad42 got lots of practice running the ovals. I can only imagine how caked the clone and F200 filters would get.

Yes, when dirt racing the air filter is pretty much the most important part of your program. Poor filter maintainence was very costly, and I had a mentor who was absolutely anal about it. I guess it rubbed off.
An additional note: When re-installing a fresh clean filter, put a dab of grease on your finger and run it around the inside of the flange, so no dirt can sneak past that way if the pipe clamp is not tight enough.
