2-Stage Intake Manifold (V-6 Engines)

What’s the Benefit?

This ingenious design enhances torque production throughout the engine’s rpm range for greater responsiveness.


The Feature:

A valve within the intake manifold opens and closes to alter the volume and shape of the chamber.

  • At lower engine speeds, the valve is closed, creating the optimum condition to take advantage of sonic resonance to help pack more of the intake charge into the combustion chamber.
  • At higher rpm, the valve opens to cancel the resonance effect and allow intake inertia to fill the cylinders more effectively.
