HOW DO THEY WORK?


Like a two part epoxy, the air/fuel mixture in your engine needs to be a specific ratio of air to fuel, in order for it to work properly. Your vehicle's EFI system constantly adjusts this ratio to best suite the environmental and driving conditions at any given moment. If your engine needs more air, and your throttle body can't meet that need, your overall performance diminishes. 
At partial throttle, a negative pressure zone forms on the upper back side of the throttle blade. Since air will always flow to a low pressure area, incoming air gets drawn to it, like a vacuum. This low pressure condition creates turbulence, which slow down the introduction of air in to your intake manifold. Less available air means, less available power.


Torque-Curve's unique port design affects airflow in your engine's throttle body, by eliminating this low pressure area, and speeding up the introduction of air in to your intake manifold. Ultimately this improves your engine's performance and fuel efficiency. Our exclusive Torque-Curve design spacers far surpass all other spacers in both performance and popularity.
