Obviously easy to install as it simply replaces the old filter. I saw an increase of 1 mile per gallon - which for my 8.1 liter GMC truck was nearly a 10% boost in MPG performance. I've asked my wife for the full K&N cone shaped free air flow filter conversion kit for Christmas. If this simple replacement filter helps my MPG this much, the conversion kit to the cone shaped filter should be great. This is the second time I've converted a vehcile to K&N and I've been totally pleased each time.
