Are Fog Machine Spark Plugs Universal?

[OliveRose]

Fog machine spark plugs are not universal. The main types of spark plugs include: standard spark plugs, projected insulator spark plugs, electrode spark plugs, seat spark plugs, pole spark plugs, and surface gap spark plugs. Steps for replacing spark plugs: Open the engine hood, lift the plastic cover of the engine, remove the high-voltage ignition wires, and mark the position of each cylinder to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris like leaves or dust and ensure they are thoroughly cleaned. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the removed high-voltage ignition wires in the firing order and secure the cover.
