5. Inspect the spark plug. Replace the
spark plug if the electrodes are worn or
if the insulators are cracked or
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/BR7HS-10 (40D2)
NGK B8HS-10/BR8HS-10 (50D2)
1. Electrode
2. Spark gap (0.9–1.0 mm, 0.035–0.039 in)
7. Install the spark plug by hand and turn
it carefully to avoid cross-threading.
8. Tighten the spark plug to the specified
torque.

Note
z Spark plug torque:
27.0 Nm (20 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.
