•  The S-DAIS increases intake air amount and combustion efficiency by controlling the size of the intake ports and the air length in the intake pipes according to engine condition. By a combination of the S-DAIS and side intake and exhaust port configuration, high torque and high output are obtained at a wide range of engine speeds from low to high.

•  For a description of S-DAIS control, refer to S-DAIS control (See SEQUENTIAL DYNAMIC AIR INTAKE SYSTEM (S-DAIS) CONTROL OUTLINE [13B-MSP].) (See SEQUENTIAL DYNAMIC AIR INTAKE SYSTEM (S-DAIS) CONTROL BLOCK DIAGRAM [13B-MSP].) (See SEQUENTIAL DYNAMIC AIR INTAKE SYSTEM (S-DAIS) CONTROL OPERATION [13B-MSP].)
