SPARK PLUG CONSTRUCTION [L3]
BUE011818110N01
• Iridium spark plugs with excellent durability and firing performance have been adopted.
• The extremely thin, center electrode has a diameter of 0.6 mm {0.023 in} and is made of iridium alloy. Durability also has been improved by the use of a platinum-tipped grounding electrode.
• By adopting the thinner (center electrode), the electric potential concentrates on the end of the electrode, therefore, the electric field is strengthened and the sparking voltage is lowered. As a result, stable combustion under any driving conditions has been obtained, and engine startability and acceleration performance have been improved. Additionally, based on the thinner center electrode, cold sparking has been reduced, and stable ignition performance under any driving conditions has been realized.
