I love my CAI inc. It looks great, sounds great & makes Ruby Goooooooooooo! I have not had to clean/oil my filter yet. If you are that worried about it get someone who knows what they are doing help you with it the first time. I thought about just getting a new filter when the time comes but folks I have talked to tell me I can do it with no problem Soooooooooooooo I guess I'll get brave & try it one of these days.
