Spark plug condition is indicative of engine operation. The spark plug
firing end condition should be read after the engine is warmed up and
the vehicle is driven at higher speeds. Immediately check the spark
plug for correct color.
WARNING
A hot exhaust system and engine can cause serious burns. Wear
protective gloves when removing a spark plug for inspection.
1. Normal
The normal insulator tip is gray, tan or light brown. There will be few
combustion deposits. The electrodes are not burned or eroded. This
indicates the proper type and heat range for the engine and the service.
NOTE: The tip should not be white. A white insulator tip indicates
overheating, caused by use of an improper spark plug or
incorrect throttle body adjustments.
