k & n filter box? Can you give me some more info on this.

Also with spills, something that i'm particularly fond of is castro superclean. It's a highly concentrated purple solution. after the spillage wipe it well, spray it with the superclean, dilute to specifications or leave a bit stronger and spray the underside let it sit for 5 min and hose off...i'll look new!! if you don't dilute it, it'll eat thru paint hoses and everything else. Use it to clean the truck quad and jeep. Works better than simple green. My o2 cents
