Perfect! My car doesn't sleep anymore and takes the gas immediately. You can feel it and also hear it. I think this filter is the first and last step to upgrade your car. You dont need anything else. Good job K&N, Thumbs up!

Installed this in a 2000 C230 Kompressor, gas mileage has improved, throttle response has improved, and the supercharger is much more audible. Thanks!

Bought 2, one for a ml 320 and one for a ml 430. Both fit great.
