A TRD supercharger is an aftermarket forced induction system that increases the power output of an engine by compressing air that is delivered to the cylinders. It typically consists of a Roots-type blower, an intercooler, and all necessary brackets, pulleys, and hoses. When installed on a Toyota Tacoma truck equipped with the 4.0L V6 engine, it can increase power by up to 60 horsepower and torque by up to 50 lb-ft.
