I recently purchased the K&N drop-in filter for my '13 Honda CR-Z and love it. Before installing the filter I logged my car's performance using Torque, and then again after installing the filter. The difference in performance was not only noticeable within Torque, but I can feel the difference while driving.

The fit was not perfect, it was a little too big but still fit with a little convincing. It really woke my 2000 Honda Shadow VLX600 up. I was really impressed with how much of an improvement it was. I would buy another K&N filter.
David, Latrobe, Pennsylvania
I own a Honda Shadow Spirit 750c2. Easy to install and immediately when I started the motor I could hear my exhaust tone had changed. When I rode it, I felt my power had increased and the transmission was able to wind out longer without straining for the first time ever. Thanks for the excellent air filter.
