1 or 2 step colder plugs?

Thinking about pulling the trigger on the plugs Dembflyr mentioned for the MHI TT kit I have on order (50003-M40HL). Still a good idea? Any special Gapping specs?

It is a good idea. And I run stock GTR plugs mine. However when I pulled my stock plugs out they were the same part/model # as the GTR plugs I was about to put in...so just check first. Might have no need for them unless you are high mileage.
