K&N Engine Air Filter: High Performance, Premium, Washable, Replacement Filter: 2004-2009 Dodge/Chrysler (Durango, Aspen), 33-2288

Customer Feedback I installed a K&N Air Filter on my 2004 Dodge Durango with a 5.7 Hemi engine. It was rated at 18-19 mpg highway, however, after installing this air filter I set the cruise at 70MPH and drove for 75 miles, never having the occasion to alter the speed, and was averaging between 22.7 and 23.1 during the entire trip. In the 3 years since installing it I am extremely satisfied with the increased gas mileage I get, so much so, that I have also installed one on my 2001 Chevrolet Suburban (w/5.3 liter engine), and my 2007 Chrysler 300C, also with a 5.7 MDE Hemi engine. I have consistently recommended K&N Air Filters to friends and family alike, and will install them on every vehicle I buy in the future. Their additional cost over a regular air filer is quickly recovered in saving, not only by increased gas mileage, but never having to buy another one as long as I own the vehicle on which I have installed them.
