• 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 01–40–14 SEQUENTIAL DYNAMIC AIR
INTAKE SYSTEM (S-DAIS) CONTROL OUTLINE.).
