Hey Kev, any clues about how often the filter needs cleaning and oiling? I forget the brand name but before installing RamAir I had a foam oil type cleaner that came with a spray can of oil. Wonder if I can use that same spray on oil.....? Can I clean the filter by dunking in a bath of liquid Dawn? Or for that matter, optionally, can I just run the filter with no oil? Seems to me I read somewhere RamAir comes pre-oiled. I really can't tell, seems dry to me.
