colder spark plugs

[north puller]

I have been running autolite 3116 plugs, and I like the projected tip design, but they are a little hot. Is there any type of projected tip plug in a champion D16 heat range, or something colder than the autolite 3116?

Go to a parts store and look at their champion plug book it will list plugs by heat range and also a conversion chart. They might even give you one.

386 is the same as a D21, Hotter than a D18

Try this again
386 = D16
3116 = D18
