Nicholas Mazmanian, Kitchener, Canada
Shipping was very quick. Didn't have to tune bike. Just replaced the stock filiter. I like that it still uses the stock cover because I park my bike outside in a parking lot. Nobody will unbolt my filiter and run away with it. Bike sounds slightly cooler. I think it runs a bit hotter, but hard to tell.

Unit works well. Install was easy and fitment was perfect.

Very easy to install and you can hear volume of air going thru the filter unlike the HD filter which is literally 4 inches of fiber cloth. Engine runs great and ther is just a touch of power you can feel on the trottle. Took less than 15 minutes to install.
