Air Density Makes Power

The boost tubes ( charge air cooler pipes) on your Diesel pickup were designed to move pressurized air through the intake system while keeping sound to a minimum. The manufacturer’s attempt to reduce sound often results in a loss of air density to the intake manifold. While the stock tubes are designed to be compact for manufacturability and ease of installation at the factory, the small diameter further restricts airflow. By contrast, Banks boost tubes are often an inch or more larger in diameter and mandrel bent to prevent pressure loss. The result is improved throttle response thanks to their superior boost retention. Erik explains just what goes into making better boost tubes.
