Very simple catalogue look-up and incredibly fast delivery, especially since I'm in Canada. The filter fit perfectly and is working well. Can't say I feel any power increase but I believe a Dyno run would prove there is some. Do feel a better throttle response and am confident of the air-cleaning. Been riding and competing since the '70s - never heard anything but good of K&N, (other than the usual fools).
