I've wondered the same thing. I also run a DPR8EA-9. Seems to be fine in the winter when it's in the 40's to the summer when it's over 100.

The heat range is only for the plug. It doesn't do much for the rest of the engine.

Can someone else comment what a coolder plug would do in the heat of the summer when it's 100? I have noticed that my XR600 is more prone to pinging when it's hot. Would a colder plug help?
