    Air induction part products

    Air induction systems

    By developing engine intake parts such as the air cleaner, intake manifold and cylinder head cover as a single system, lighter weight and a compact design is realized while also contributing to improved engine performance.

    Air cleaners

    High-performance type
    High-performance type

    These remove dirt, dust and sand and other debris in the air that enter the engine. The compact nature of high-performance air cleaners enables maximum use of limited space inside the engine room.

    Intake manifolds

    Horizontally opposed engine type
    Horizontally opposed engine type

    Air drawn in from the throttle is dispersed to each engine cylinder. The use of plastic helps realise considerable weight reduction and facilitate use in a wide range of engines, from straight engines to horizontally opposed engines.

    Cylinder head covers

    Plastic type
    Plastic type

    These cover the valve on top of the engine cylinder head and prevent engine oil and unburned gas from leaking. Fitted with an OCV (Oil Control Valve) that optimises the timing for opening and closing the valve for air intake and emission.
