    Fitting instructions

    - Choose a spark plug with an electrode gap of 0.7 mm (standard) or regulate the gap accordingly.

    - Always clean the cylinder head before removing an old spark plug.

    - Remove the old spark plug.

    - Start by screwing in the new spark plug by hand and then tighten to the correct torque using a torque wrench (refer to separate box).

    - Apply the insulating paste directly to the connector.

    - Attach the connector.

    • Tightening torque (N • m): 10 N • m ˜ 1 kpm for dry, non-greased/non-oiled threads and new seals.
    • Reduce the torque by 1/3 for lubricated threads or on re-installation.
