James Smith, Michigan
I have been using K&N filters on all of my cars for over 10 years. I highly recommend this product to everyone. This filter is easy to install and is much thinner than the filter that the factory uses and gives more air to the engine giving it a little more boost. Gas mileage has seen a little more improvement since installing this filter.
