      So I read how it says Off Road. So I am confused does it mean Off Road or for racing?

      • The term "Off-Road" when speaking about products for our mustangs means that the part in question is not legal for use upon road or legal for inspection/emission purposed. The term "Off-Road" does not refer to taking the Mustang threw a creek or climbing your local sand dunes if that was your concern.

      Will it damage the Procharger to ride in the street? It’s not a daily driver it’s a Street/strip car weekend play toy.

      • The Procharger High Output Intercooled Supercharger Kit - F-1R 12 Rib is recommended for race-use only as it is not street legal in many states with inspection/emission restrictions. It will not cause any damage to your vehicle to run on the street.
