Dieter Bernhart, Barringto, New Jersey
Have been using K&N filters for the last four cars I have owned. These filters are as described. Would not use any other.

Such a vast improvement over the stock air filter. Perfect fit as always.

Great filter! Slight but noticeable improvement in acceleration and fuel economy. Far better made than OEM filters, no comparison! Reusability is important too, as it reduces waste and frequency of cleaning is no problem. I have recommended this brand of air filter to friends looking to improve performance and/or fuel economy. Over the long haul, the item more than pays for itself.
