5. Inspect the spark plug. Replace the
spark plug if the electrodes are worn or
i f t h e i n s u l a t o r s a r e c r a c k e d o r
chipped.
6. Measure the spark plug electrode gap
with a wire type feeler gauge. The gap
should be 0.9-1.0 mm (0.035-0.039
inches). If the gap is different, replace
the spark plug with a new one
Use spark plug NGK B7HS-10 or
BR7HS10.

Note
Spark plug torque:
27.0 Nm (20.0 ft-lb) [2.7 kgf-m]
If a torque-wrench is not available when you
are fitting a spark plug, a good estimate of
the correct torque is 1/4 to 1/2 a turn past
finger-tight. Have the spark plug adjusted to
the correct torque as soon as possible with
a torque-wrench.
