in champion and autolite the higher the # the hotter the plug. d21 is hotter than d16. plus when you look at the plugs the electrode on a hotter plug will be thinner. plus there is the longer reach ones also, which is the 15y I believe.the harder you work the engine the colder plug you would go , to reason.

The answer from barnyard is correct. If it is fouling plugs, especially if only one cylinder, putting a full set in it may cause detonation that can take out the pistons. If it is getting loader work, or parades, it would be OK. If you are running 87 octane 10% ethanol, running premium will also curb knock. Jim

Champion D21 is the classic hot plug, but a lot of people don't like Champions. You can cross reference that to an autolite with google.
