Have used K&N filters in all of my cars for the last 25 years! My most recent was for my new 2014 Fiesta ST. They're just the best filters!

Have had increased performance and very satisfied since installing the KN Air Filter. We have a 2012 Ford Fiesta 4 Cyl. that no longer has a hard time taking the steep hills in our terrain Vehicle has more HP in freeway driving when needed.
Adam, Phoenix, Arizona
Have always liked K&N products. Just swapped out the stock filter on a 2014 Fiesta for this and there's a noticeable improvement in acceleration. Definitely plan on going K&N for my truck when the filter's due. Good quality brand and fast shipping.
