Bought the filter for my new car, a 2014 Honda Accord Coupe, V-6. I have put K&N air filters in all my cars since about 2001. I find they increase top end power and help throttle response at lower rpms, and they usually improve gas mileage as well. Thanks for your great products.

Purchased this filter for my 2012 Honda Accord. Perfect fit! Substantially quicker on acceleration! Also ordered one for my Civic & CRV! Thanks!
Mike Mackrell, Fredericksburg, Verginia
I have used these filters for many years and have always been pleased with the improvement they make in the performance of the engine. This one was something I had to wait for as the Honda Accord was a new model. I had 13,000 miles on the original air filter before I installed the KN drop in. This initial impression is a feeling of smoothness in acceleration in traffic. This engine has cylinder deactivation (runs on 3 at times) and that really improved. Gas milage has improved in traffic by 1 mpg and today I actually calculated 38.9 mpg on steady highway running going to FLA. I was running 75-80 on the interstate. Impressive for a V-6. Honda should make these filters OEM!
