Great filter...use it to my other 2 current vehicles. I always replace my OEM filters with K&N because of the added performance it gives to the vehicle. Highly recommended for all vehicles!

I like my new filters. I have noticed a 1-2 mpg increase in my vehicle so far. I really like the fact that I will never have replace the filter for the entire life of the car, just clean the kn filter. Awesome.
