This is the fourth filter I have bought.
The last filter (for a 2014 2.0 Ecoboost)
has increased mileage 5 to 6 miles per gallon.
Very Happy.

I have left many reviews on the products I installed in my car and family's cars in the past. This past week I got the replacement filter for my girlfriend's 2012 Ford Focus SE along with an oil change to Royal Purple and used one of your oil filters. The car already had a muffler and resonator delete so both the oil change and the air filter made it sound even more aggresive. The biggest benefits are to performance and driveability to the vehicle though. On the freeway it got a best tank of 46.5 MPG averaging a little over 70 MPH and it makes the dual clutch transmission shift ALOT smoother so it doesn't feel so much like a teenager learning a manual at low speeds haha. Thank you for another great product and all the extra performance and fuel economy your filters always give. I will always use K&N in all of my vehicles

This is my third vehicle only using k&n filters. I am getting an easy 1.5 extra mpg on average after 1500 miles driven since installation. I will never own another vehicle without buying a K&N filter. The extra pep was noticed right away in the pedal. Better mpg, better performance. It only makes since to use K&N filters.
