Gapping Spark Plugs

I am getting ready to change out some spark plugs on my PA28-180 due to fouling on my right mag. I will be putting in massive REM37BY to replace REM38E at the recommendation of Lycoming. The issue is that the right mag check is increasingly fouled when doing run up. It will clear but even with aggressive leaning it is usually fouled. So the plan is to change two on one side fired with the right mag and if that doesn't solve it then move the new plugs to the other side served by the right mag.

But, the real reason for posting is to ask about gapping spark plugs. Are they gapped when you get them? If I need to gap them then can they be gapped with standard automotive wire gauge set? I've gapped many auto style plugs but never aircraft types.
Any advise welcome.

  • Yes, they should be gaped when you get them. I just put them in. I would get Tempest plugs.

    Lean all the time, ground, and any altitude in flight.
