In terms of basic structure, the intake manifold are the same as the 4G6 engine intake manifold used in the SPACE RUNNER and SPACE WAGON.

    The aluminum inlet manifold equipped with the EGR passage is adopted.

    The intake manifold is designed to improve the low, middle and high torque by optimizing the port diameter and length. A port opening with an optimized bell mouth shape and improved the inside roughness of the port reduces airflow resistance.
