Let it flow.

Banks Big Hoss Bundle replaces the power-robbing factory airflow inefficiencies—including the intercooler—with free-flowing components that dramatically increase intake airflow and air density and expel exhaust with virtually no backpressure.

Colossal power with staying power.

Banks balances the improved airflow with advanced CleanTune™ Technology that adds up to 54% more horsepower and up to 68% more torque than stock without adding black smoke. This is tire-shredding, scenery-blurring constant-duty power that keeps its cool while blasting you from 0-60 mph 24% quicker and 148 feet before stock!

The secret to longer life.

Forget mis-matched components. Run away from tuners that can destroy your engine. Everything in the Big Hoss Bundle is engineered to work together to maximize your engine’s power, efficiency and durability. Big Hoss honors your vehicle by safely living within the limits of your engine. Your Duramax will run stronger and live longer!
