Yo guys, I'm out of a job right now so I have no money. I've had my Tib for over a year now and want to start with the K&N Filter. I was wondering if any of you guys out there with the K&N filter notice any big difference in performance. I'm thinking of buying it after reading all of the testimonials and hearing from a friend but I want to be sure. Also, how much did you guys spend for it? Thanks........
