That is not entirely true. Some plugs have no way to be gapped. An example would be of the plugs found in some rotary engines in the RX's. As stated above, if you are going to gap them and check the gap, use the right tool. Do not use the old round tapered gapper or you can ruin a new plug. I have found most factory plugs are already pre-gapped correctly.

E3's don't get gapped, like a lot of other plugs.

Incorrect. There are several plugs including iridium plugs that are "do not gap" plugs. Gapping such plugs can cause damage and not allow them to function properly.
