I've always done these with the K&N filter service kit. It has cleaning fluid and oil in it. But, to be honest, I'm not sure that that's the right thing to do. Seemed to work though. :)

yep just wash in a bucket with soapy water.. the re-oil with a foam filter oil.. try not to use the K+N type oil as it is too thin for a foam filter.

I know but it's what's on the K&N and it seems to be OK.

i use something called a 'dust retention coating' which i dont think is as bad as the oil based stuff.. its comes out of the can as a foam...

just do a google for 'foam filter oil' and read up on why not to use oil based one... theres loads of products out there too..
