Glacier Diesel Power - 2003 thru 2007 Dodge Ram - S&B

The air filter assembly is where your power quest begins. Without proper airflow your Cummins simply cannot burn the available fuel, resulting in poor performance and fuel economy, not to mention high exhaust gas temperatures (EGT's). While the design of the stock intake system is relatively efficient, upgrading to a higher flowing aftermarket system can drastically improve overall airflow, delivering better overall engine performance, efficiency, and lower EGT's.
