Signs of a faulty part

If you notice any of the following, the part likely needs replacement:

  • Loss of power or torque in certain rev ranges
  • Check Engine light with an intake runner control fault code
  • Rattling noise from the intake manifold area

Installation information

Bolts to the intake manifold with a seal, and connects to a vacuum line or electrical actuator — check the actuator moves freely before finishing installation.

Frequently asked questions

It physically changes the length of the intake runners — shorter for high-RPM power, longer for low-RPM torque — giving the engine better response across the whole rev range.
