"My 2001 Dodge Cummins Diesel MPG went from 14.3 to 15.6 around town. I have yet to run down the freeway but I expect at least 5% increase going down the Interstate empty or with my 31 ft trailer attached. I am only sorry I didn't get the K and N intake system. I beleive its coming before we go to AZ with the trailer this coming fall for our winter stay." —Donald B from Spanaway, WA bought a K&N Air Filters for a 2001 Dodge Ram, 2500, 5.9L Cummins.
