I received a marked improvement in the responsiveness of my BMW immediately after installing the K&N. Leaving stop lights the car's rear wheels broke loose several times. It was necessary to adjust the way I accelerated the car to avoid this from happening. The car had never done that before. Highway 0-60 has improved also. It has given new life to an old car. Wish I'd put the K&N filter in years ago.
