Hey everyone i recently purchased a KN proseries airfilter and was wondering some things about it. It is the paper one and not the foam one.( I hope i didnt already go wrong with purchasing that one) But i heard you spray them with some type of sticky stuff. Now is that true or you dont spray the paper ones, or do you spray the inside of your air box? I was also just wondering how you guys feel about the paper compared to the foam ones. I see alot of people with foam so thats why i was just wondering. Thanks againn
