This modification involves removing the factory-installed component designed to regulate airflow into the intake manifold of a 6.7-liter Powerstroke diesel engine. This component, often referred to as a throttle valve, can be physically removed and replaced with aftermarket hardware to allow for unrestricted airflow. The purpose is to eliminate a potential point of restriction in the intake system.
The importance of this alteration stems from potential enhancements in engine performance and reliability. By removing a possible obstruction to airflow, it’s purported to improve throttle response, leading to increased power output and fuel efficiency. Furthermore, some believe removing the factory component can eliminate a source of potential mechanical failure associated with its original design. Historically, modifications like these have been popular within the diesel performance community seeking to maximize engine output.
