Denso Iridium Spark Plug - iQ 1.0

The thread diameter is 12mm with a length of 26.5mm, and a 16mm hexagon.
Plug gap: 1.1
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 ground electrode, creates a spark plug that is almost impervious to wear even under extreme driving or racing conditions.
