K&N 33-2247 Air Filter Product Reviews

Seems like it added a little kick to my Dodge. Hope it even gets better.

With 14,000 miles on a 2015 RAM 1500 with the 3.0 Ecodiesel, I noticed an IMMEDIATE increase in throttle response. The K&N also changed the intake sound from nothing to a low growl during acceleration, but while cruising. A 320 mile trip two weeks prior to changing the air filter netted me about 25.6 mpg. Last week on the same trip (both times cruise control set at 73 mph and same time of day) I broke a record of 29.7 mpg. EPA ratings on this vehicle for highway are 28 mpg. The K&N did make a huge difference.

Prompt shipping and product was in excellent shape, no touch up oiling needed. Installation was a breeze. Would definitely recommend this site to a friend.
