The cure for airflow restriction.
The stock LBZ engine is riddled with airflow bottlenecks-including the intercooler. PowerPack replaces them with free-flowing components that dramatically increase intake airflow and air density and expel exhaust with virtually no backpressure.
Colossal power stays cool, sips fuel.
All that improved airflow is then balanced with Banks' comprehensive CleanTune™ Technology for 31% more HP and 35% more torque than stock. This is load-hauling, hill-flattening constant-duty power that keeps its cool. It'll chop a football field off your 40-60 mph acceleration distance when towing, without adding black smoke. And your fuel economy will improve, as well. Sweet!
The Banks difference? Engineering.
Forget mis-matched components. Run away from tuners that can destroy your engine. Everything in PowerPack is engineered to work together to maximize your engine's power, efficiency and durability. PowerPack honors your vehicle by safely living within the limits of your engine and powertrain. Your Duramax will run stronger and live longer!
All gains measured at the rear wheels.
