Denso Double Platinum Spark Plug Multi-ground electrodes and a platinum center electrode are another long life plug. The platinum tip on the center electrode will extend its life, while having more than one ground electrode also offers extended ground electrode life. Copper core for better thermal c...

Iridium plugs have an extremely long life as Iridium is 6x harder and 8x stronger than platinum. Because of the strength and hardness of iridium, there is virtually no electrode wear. This combined with a platinum tipped ground electrode, creates a spark plug that is almost impervious to wear even u...
