Can of mineral spirits and a bucket. If it's not too ridiculously dirty, you can just pour it from the bucket right back into the can and reuse several, several times (the sediment will settle in the bottom of the bucket).

A K&N .

 

I use dawn dish soap and hot water on my 02 stock one and air blow dry it and reoil

 

I use Wisk laundry detergent in a bucket of hot water. It works well as long as you keep up on them.
