Iridium and Platinum tipped spark plugs Do not gap Do not clean Do not remove The only “maintenance” is replacement. The gap should be adjusted by only moving the ground electrode. This may be for combustion chamber design as in the case of a rotary engine, or a surface gap design as used in leaner air/fuel ratio’s on industrial engines. Look closely at the plug electrodes in the cylinder head picture I included. It's only said to help the gas vaporize better so it ignites faster and more complete. For the most part you will have to do the reading. The spark plug is the life source in an engine. Properly bolt down the spark plug so that you don't have to hold it by hand when you use the dremel.
