Beautiful filters and excellent fit. Happy with my purchase. Replaced my dirty OEM filters on my Suzuki M109R motorcycle with them. Simple acceleration runs before and after showed no difference in performance. No matter. Still happy with them.

The product is nice and the delivery was fast but the box was destroyed when received. So bad that i was supprised that the filters were still good. One was bent on the frame but I could still use it. Still an excellent buy at a good price with shipping to Canada.
