By inserting the D3 spacer, the air calms down allowing the passage through the Supercharger without the unwanted turbulence. The result is a more efficient factory brick supercharger while keeping the factory unit in place rather than replacing it with a less efficient unit. The D3 Supercharger Lid Spacer will increase plenum capacity by 63 cubic inches – significantly reducing the turbulence inside the supercharger lid and increasing raw horsepower by a Dyno proven 7.5 HP to the wheels. This comes with new mounting hardware and will clear the factory engine brace without modification.
Without the spacer in place, over boosted vehicles will experience a choke inside of the Supercharger lid. The air inside can become turbulent to the point where it starts to restrict airflow. Turbulence causes friction and heat, thus decreasing the thermal efficiency of the compressed air.
