Awesome as always.

Great filter! Slight but noticeable improvement in acceleration and fuel economy. Far better made than OEM filters, no comparison! Reusability is important too, as it reduces waste and frequency of cleaning is no problem. I have recommended this brand of air filter to friends looking to improve performance and/or fuel economy. Over the long haul, the item more than pays for itself.

Have been using your product for many years, and have nothing but positive things to say about K & N Filters. Had them in a 99 Crown Vic, with Hi performance engine, 97 s-10 pick-up, 4.3. Two Mercury Grand Marque, 06 Chevrolet Silverado 1500, and now this last auto, 2013 Fusion.  Have been using K&N Filters long enough, to have had to buy, two cleaning kits.  My Son, son-in-Law, his wife, and others in my family, all use these Filters, and will continue to do so, far as long as I am able to drive.  I have, and will continue to recommend your product.
