Product Reviews

  I just put a K&N in my 2012 Kia Optima tubo, what a differance in takeoff and passing I've allways been a big fan of K&N.
Chuck Chatsworth, California
  Purchased air filter and put it in my car right before I went on a 1000 mile road trip over the Rocky Mountains into Denver. My car's acceleration picked up, smoother drive, less engine noise, pick up is great. I can definitely tell the difference. The car is so much more smoother than ever before.

  I have had great success with K&N filters in the past. I am already gaining 2 mpg on my Hyundai Sonata by switching filters.

  I have a K&N Air Filter on my 2011 Kia Optima for about a year and 1/2. I like that I don't have them trying to sell me a new filter every time I get an oil change. I just ordered a K&N Cabin Air Filter too.
Walter Read Kingston, New York
  Excellent filter so far with the turbo Optima. It give it lower end performance.
Jere Mack Marengo, Illinois
  Nothing but the best for my new car. Love K&N filters.
Cory Giles Orlando, Florida
  I had always heard good reports about these filters and decided to try one. My car typically gets 30 mpg. Recently it was getting 27. With the new filter it is 34-35. I'm a sceptic but have to say this filter works.
