Turbulence is created when then engine is running at partial throttle and a negative pressure zone forms on the upper backside of the throttle blade. Since air flows to a low pressure area, the incoming air gets drawn down to it like a vacuum. This low pressure condition slows the introduction of air into the intake manifold, producing less available air resulting reduced power.

The unique design of Hamburger's Torque-Curve port affects airflow in the engine's throttle body. By eliminating the low pressure area and accelerating air flow into the intake manifold, you will gain engine performance and fuel efficiency. These spacers are dyno proven, surpassing all others in results and popularity. .
