Hamburger's TORQUE-CURVE MPFI Spacer

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. Torque-Curve Technology allows more air to be sucked into the engine, recovering much of this lost torque.
