    1. Long-reach type spark plugs are used. This type of spark plug allows the area of the cylinder head sub-assembly that receives the spark plugs to be made thicker. As a result, the cylinder head water jacket can be extended near the combustion chamber, which contributes to cooling performance.

    2. The triple ground electrode type iridium-tipped spark plugs are used to achieve a 100000 km (60000 mile) maintenance interval. By making the tip of the electrode out of iridium, it is possible to achieve superior ignition performance and durability when compared to platinum-tipped spark plugs. Furthermore, 2 ground electrodes have been added to further enhance ignitability, wear resistance, and fouling resistance.
