thickness gauge and, if necessary, adjust
the gap to specification.
2. Clean the gasket surface. Wipe off any
grime from the threads.
3. Install the spark plug and tighten it to the
specified torque.NOTE:If a torque wrench is not available when you
are installing a spark plug, a good estimate of
the correct torque is 1/4 to 1/2 turn past finger
tight. Have the spark plug tightened to thespecified torque as soon as possible.
4. Install the spark plug cap.Spark plug gap:
0.6 ~ 0.7 mm
Tightening torque:
Spark plug:
