Rolls eyes. I love that people don't get the difference. This car has untouched fuel system, oil system, cooling system, suspension, drivetrain. All they did was BOLT ON the supercharger there ARE ZERO modifications or complex tools used to install this. It is EASIER to install than almost ANY modification and comes preloaded with tunes. I don't see how you guys don't understand this. It's night and day different from old school super and turbo chargers.
