"K&N air filters are simply the best. I have been using them in every single gas motor I own. They have always added power, and sometimes helped with MPG. But the fact you can wash them reoil, and reuse them saves money in the long run. I will not use anything else!" —Jeremy K from Hilliard, OH bought a K&N Air Filters for a 2011 Ford F-150.
"During theses times of high and higher gas prices, this was the best thing that I have ever done. Since I installed the K & N filter my gas mileage has improved about 25%. My 2008 ford f250 super duty was only getting about 9.5 mpg on average. Now with the K&N air filter installed I am averaging between 13.4 - 14.8. Wish I could have install the cold air intake system, imagine what I could be getting in MPG. Thanks for asking me for this review.
