to remove the spark plug.
3. Check for discoloration and remove the carbon. The porcelain insulator
around the center electrode of spark plug should be a medium-to-light
tan color.
4. Check the spark plug type and gap.
Standard Spark Plug:
TORCH-A5RTC/E6TC/E6RTC
Spark Plug Gap: 0.6-0.8mm (0.024-0.028in)
TIP: The spark plug gap should be measured with a wire thickness
gauge and, If necessary, adjusted to specification.
5. Install the spark plug.
Spark Plug Torque: 12.5 N*m (1.25 kgf*m, 9 lbf*ft)
TIP: If a torque wrench is not available when installing a spark plug, a
good estimate of the correct torque is 1/4-1/2 turn past finger tight.
However, the spark plug should be tightened to the specified torque as
soon as possible.
