K&N direct had the best prices and got the filter out to me right away. I selected 2-day air so I could have it for a race. My motorcycle had a some kind of a reusable foam filter that had deteriorated and I've never had that problem with a K&N. Go with what you know

Great service from the company. Very noticeable gain in performance. Was skeptical of one reviewer's claim of product changing the way the bike sounds, but it a good way! Wish I would had installed one 45,000 miles ago!

I am doing up a 03 SV650 and am impressed with the K+N air filter (SU-6503). The bike sounds and runs better. It is also operating smoother across the rev range. I like the filters ability to be reconditioned in the future.

Thanks K+N
