2. Insert shaft (3) into tool (4) and turn counterclockwise 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.
6. Install the spark plug cap and spark plug cover.
