Product arrived very quickly, packaged very securely w/detailed instructions. Results were immediately noticed and I purchased the recommended servicing package from K&N so I could perform the maintenance when needed. Now I want to find a service provider to assist me with installing the complete cool air intake K&N system. Thanks for the product and prompt service. For the record I have had your products on several vehicles Autos, trucks and Motorcycles both foreign and domestic, the experience has always been a good one.

Withholding fifth star because I just recently installed the filter. Great so far. Easy installation, perfect fit in my Civic SI. I seem to notice a bit of torque increase, and a tiny bit more intake noise, but not a problem. I have K&N's in both my motorcycles, and have had good experiences with these and earlier applications.
