"I recently installed a K&N filter on my 2004 Ford Explorer at 20,000 miles. It seems that the throttle is more responsive, no noticable lag at all. I am very pleased with the results of replacing the filter with the K&N. Gas milage seems a bit better too as long as I am not trying to see how much extra power that is has gained! Averaged nearly 21 mpg on a recent road trip, over 16 in the city. Not great milage, but I can live with it." —Timothy O from Litchfield, NH bought a K&N Air Filters for a 2004 Ford Explorer.

"I have just installed a K&N filter in my 2004 Ford Explorer V8 and I now have K&N's in all my vehicles; I like the thought that it improves breathing, never needs to be replaced (only cleaned) and ostensibly adds a few horses! My Explorer feels livelier (whether or not that is only in my mind) I am a believer and if you are a car guy and do not want to spend money on a K&N cold air intake system, get the K&N filter, it is great! By the way, shop AutoAnything for the best price anywhere on a K&N!" —Francois W from Burlington, ON bought a K&N Air Filters for a 2004 Ford Explorer.
