 I bought this filter to see if I could increase my mileage. I was shocked at a 10% increase in MPG. My 2013 Accord V6 manual was getting 27-28 on the Hwy with the stock air cleaner. When I put in the K&N filter I am now getting 31-32 MPG. I once tried to drive real easy just to see how good I could get for mileage and once got 34.3 MPG. This car doesn't need any more power at almost 280 horse it's almost too much for front wheel drive, but it's fun when you want it. Highly recommend this product. Oh I even put a K&N filter in my wife's 2014 Mazda 6 and have seen similar results. Great filter. Again highly recommend.

 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.

 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!
