Yep thats them Iridiums. Sweet plugs. Unfortunatley I run 17 of them in all except one of my petrol powered engines. 1 in the kx,2 for the road bike, 6 for the alfa, 8 in the ute! $22 each. But they do last and provide good spark.
Yep working every day Kiwi. Truck is in the repair shop. hope to get it back end of next week. Still got me other old banger to give me something to do during the day.
