Reviews for: Air Filter, K&N

If you're a fan of K&N and have a stock bike and want a lifetime filter, this may be ok. But when turning the carb I found this was much more restrictive than the OEM or other foam filters. If you look at it, it's obvious they filled in a lot of filter surface area with rubber gasketing so they could get this small rectangular filter the right shape to fit. I couldn't solve the rich condition I was having till I went back to the foam filter. Shame on K&N saying this filter improves flow because it's actually restricting it.
