Intake Manifold Tuning Valve
The Intake Manifold Tuning Valve (IMTV) is located at the front right hand side of the air intake manifold. The IMTV is
controlled by a PWM signal from the ECM For additional information, refer to

(303-14A
Electronic Engine Controls - 4.0L)
. The IMTV moves a plate within the inlet manifold to allow or block sonic pulses between the split manifold halves. This,
in effect, extends the inlet runners and optimises for better low rpm torque.
