Best filters ever made!

I have used these filters in my last three cars and they work wonderfully well. They increase the gas milage and gave the car a little more power. Very easy to clean and refresh the filter.

I just bought a K&N air filter for our 2012 Hyundai SantaFe with the 2.4 engine. I haven't used K&N for a while and forgot just how good the product is. The SantaFe had been getting about 24 MPG combined and, on a good day, about 27.5 highway. With the K&N air filter, the performance is much better and the combined mileage has gone up to about 27.7. We haven't been on the highway for any length, but have a trip planned in a couple of weeks. I expect around 30. Thanks for a fine product. I will recommend your filters to anyone!
