The intake air surge tank assembly is made of plastic to realize a lightweight construction.
The intake air surge tank assembly consists of upper and lower sections and contains an intake air control valve. This valve is activated by the Acoustic Control Induction System (ACIS) and is used to alter the intake pipe length to improve engine performance in all engine speed ranges.
The ACIS valve actuator uses a vacuum actuator and is onto the intake air surge tank.
