Have used K&N Products on my vehicles for the past 8 years. Better breathing is always better. My now 2013 Honda Accord V6 has seamless throttle response and accelerates smoothly. It previously would Charge for air and then leap forward, as now it is a very smooth motion. Fuel economy has improved as well, however I am a LEAD foot and not the example to live by. This filter is a blessing and should be the standard for base model production.
Robert, Washington
I've used K&N air filters in my last four automobiles, (a 2002 Honda Accord, 1999 Ford Explore, 2011 Highlander and 2014 CR-V,) plus two for my son's automobiles. Although I can't quantify their performance accurately, I think they improve both performance and mileage slightly. This is important to me because I now own two four cylinder cars and want all the horsepower I can get.

Shipped and received on time and filter fit perfectly. My 2013 V-6 Honda Accord runs better than ever.
