 I have been using K&N air and oil filters for years, in my cars, and Harleys. I just installed this one in my 2014 Dodge Dart Limited. I immediately noticed more power, and better mileage. K&N filters are the best, period!
Rick Williams, Missouri
 Bought this for the new car and immediately felt the difference. The Dodge Dart is a very European type small engine kind of boggy, kind of stall prone at low revs. After changing to the K&N air cleaner the low end on the engine became much stronger and a bit more throaty. The acceleration seems to be much easier and surprisingly quicker. I am very impressed. This is the third K&N filter I have purchased and will soon get another for my daughter's new car.

 This is my second K&N Air Filter. It works as advertised. I recently did a lot of driving in the country and ended up with pebbles, dirt and debris in my filter. It was nice to be able to just wash it out, oil it, and put it back in, instead of buying a new one. It's an investment up front, but I expect to have my car for well over 100,000 miles, so I know I will save money on filters in the long run.
