Perfect fit. I was having trouble finding the right filter every time it came time to change it out. Always ended up at the dealers which is 30 minute drive. This filter changed all that and I couldn't be more pleased. Great Product, excellent service.

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.
