grime from the spark plug threads.

3. Install the spark plug with the spark plug

wrench, and then tighten it to the specified
torque.

NOTE:

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.

4. Install the spark plug cap.
5. Install the panel.
