What kind of spark plug does the Mercedes-Benz E300 use?

[VanJayce]

The Mercedes-Benz E300 uses Bosch F8DC0R spark plugs, which are cost-effective standard metal spark plugs. Definition of spark plug: A spark plug is a crucial component in the ignition system of a gasoline engine. It introduces high-voltage electricity into the combustion chamber and causes it to jump across the electrode gap, generating a spark to ignite the combustible air-fuel mixture in the cylinder. Composition of spark plug: A spark plug mainly consists of a terminal nut, insulator, terminal stud, center electrode, side electrode, and metal shell, with the side electrode welded onto the shell. Spark plugs are installed on the side or top of the engine. Early spark plugs were connected to the distributor via ignition cables, but over the past decade, most passenger car engines have adopted direct coil-on-plug ignition systems where ignition coils connect directly to spark plugs.
