Spark Plug Explained - Types, Function & Replacement Guide #215072 (License: Personal Use)

This image shows a conventional resistor-type spark plug with a nickel-alloy center electrode, hexagonal nut for wrench installation, and a white alumina ceramic insulator for high-voltage isolation. The ground electrode is bent in an L-shape to create the spark gap, critical for igniting the air-fuel mixture in internal combustion engines. Designed for durability and heat dissipation, it’s suitable for most standard gasoline-powered vehicles.
