2. Check the spark plug for electrode erosion

and excessive carbon or other deposits, and
replace it if necessary.

3. Measure the spark plug gap with a wire thick-

ness gauge and, if necessary, adjust the gap
to specification.

To install the spark plug

1. Clean the surface of the spark plug gasket

and its mating surface, and then wipe off any
grime from the spark plug threads.

2. Install the spark plug with the spark plug

wrench, and then tighten it to the specified
torque.

TIP

If a torque wrench is not available when installing
the 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.

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

Specified spark plug:

NGK/DR8EA

1. Spark plug gap

Spark plug gap:

0.6–0.7 mm (0.024–0.028 in)

Tightening torque:

Spark plug:

17.5 Nm (1.75 m·kgf, 12.7 ft·lbf)
