Paul79UF New Member Oct 26, 2019 #4 Oct 26, 2019 #4 Iridium plugs are always pre-gapped from the factory. You can check them with a spark plug gap gauge tool. If the plugs don't have the correct gap, they may have been damaged in shipping. I would return them for new ones. Don't try to re-gap iridium plugs.
