Title: Seams to work, but the maintenance of product is annoying.
Review: So I appear to be getting slightly better MPG according to my last 5 fill ups. So that's a plus. I was expecting a no/low maintenance filter as advertised. But then I did some research and found out I'm supposed to be spraying the thing with 3 different cleaners/primers every so often which are also made by, you guessed it, K&N. So that was a little annoying. So add those things to your list when you buy the thing. I hate surprises.
Is the review positive or negative?
