He realizado solo unos 600 Km, con el nuevo filtro, la sensación de aceleración del motor es mas rápida y con relación al consumo, es pronto para poder valorarlo. Un saludo

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