I have purchased 4 K&N air filters. 3 for my current and past Hondas and 1 for my Triton V-10 powered motor home. I am a retired automotive technology instructor and understand the inherent advantages of this free-flowing filter.I was most impressed with the increase in power produced by my V-10 motor home engine after I replaced the OEM filter with the K&N filter. With the original filter, while towing my car behind the motor home through the Pocono Mountains, my coach downshifted 3 and 4 times on steep upgrades. After installing the K&N, on the same grades with the same load, the transmission only downshifted two and sometimes 3 times at most. Fuel economy increased 10 to 12%.

Fast shipping. Great product. Always love using K&N. It is the first upgrade I do on everyone of my vehicles.

I just installed this in my 2013 Civic EX. Instantly improved my gas mileage by 3 to 4 MPG. I have had a K&N filter in my 2001 GMC Sierra for the last 180,000 miles and it is still going strong.
