"After using the K&N products on all of my automobiles I have noticed better throttle response and a minimal improvement in power. Don't expect to get guaranteed gas mileage savings by dropping one in. One major benefit is the added power WITHOUT a decrease in fuel economy. My daily commute has me motoring up 3000ft mountain. The K&N gave my small Ford Focus the ability to climb it in fourth gear rather than third, thereby dropping engine revs, saving fuel and stopping that drowning noise created from under the hood at higher RPM's. If you're a commuter, you will enjoy a slight increase in passing power as well as a cooler running engine (more air is entering the combustion chamber therefore better completing the fuel burn resulting in less deposits that can create heat.). All of this without reducing your gas mileage." —John J from Santa Rosa, CA bought a K&N Air Filters for a 1999 Jeep Grand Cherokee.
