SPARK PLUG
The vehicle comes with a CHAMPION PRG7C spark plug. Check the color of the plug’
s porcelain center electrode insulator after vehicle operation. The ideal color on the white
insulator around the center electrode is medium-to light tan color. A white or dark insulator
indicates that the engine may need adjustment.
Periodically remove and inspect the spark plug because heat and deposits will cause the spark
plug to slowly break down and erode. Contact with your CECTEK dealer if your plug insulator is
not a light color.
Improperly use the spark plug can be hazardous.
An improper spark plug may have an incorrect fit or overheat for your vehicle. Engine
damage caused by improper spark plug is not covered by CECTEK’s warranty.
Replace the spark plug with the specied plug.
