Spark Plug: Description and Operation

RESISTOR SPARK PLUGS
All engines use resistor spark plugs. They have resistance values ranging from 6,000 to 20,000 ohms when checked with at least a 1000 volt spark plug tester.

Do not use an ohm meter to check the resistance of the spark plugs. This will give an inaccurate reading.

Refer to the Specifications for gap and type of spark plug.
