Brandan Venne, Norwood, Massachusetts
Installed this in a 2000 C230 Kompressor, gas mileage has improved, throttle response has improved, and the supercharger is much more audible. Thanks!
Sean, Long Branch, New Jersey
I'm very satisfied. I have experienced noticeable horsepower gains, and I am very happy with the fact I will never have to buy another filter.
Dairus Reynnet, Michigan
It seems to work, however, I haven't noticed any improvement in power or mileage. It hasn't seemed to degrade mileage or power, I just haven't noticed any significant change.
