AFE filters dramatically improved driveability. Horsepower was already good with a 3.5 litre V-6 in a relatively light car but throttle response is amazing. There in no longer a slight knock on start-up. Engine breathes more freely resulting in smoother transmission shifts because trans operation is linked to engine sensors. AFE met all my expectations. Have not yet checked fuel economy but I suspect that also will be marginally improved.
