Air Intake Pre-Spinner

The 4.0 L V6 Petrol Prado engine draws its air through a cyclonic pre-spinner inside the intake duct. The pre-spinner is designed to spin heavier particles from the intake air stream and deposit them inside the rubber one way valve at the bottom of the duct.

Periodically, the rubber one way valve needs to be emptied of trapped particles.

Depress the rubber valve flaps as shown above. This will release trapped deposits (dirt particles above).
