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...

Iridium plug, 14 millimeter thread size, 26.5 millimeter (1.04 inch) reach, 5/8 inch (16 millimeter) Hex size, gasket seat, resistor, extended reach, solid terminal nut, 0.7 millimeter iridium center electrode, .044 inch (1.1 millimeter) gap, heat range: 20.

Increased performance with World's smallest Iridium Center Electrode (0.4mm). To increase ignitability, the important point is to let the flame kernel produced by the spark to grow unobstructed. Normally, this can be accomplished by widening the spark gap. However, this causes spark voltage to incre...
