    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. Thus, 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 (62140 miles) maintenance interval. By making the center electrode of iridium, it is possible to achieve superior ignition performance and durability when compared to platinum-tipped spark plugs. Furthermore, two ground electrodes have been added to further enhance ignitability, wear resistance, and fouling resistance.
