and its mating surface, and then wipe off any
grime from the spark plug threads.
Tightening torque:
Spark plug:
13 Nm (1.3 m·kgf, 9.4 ft·lbf)
TIP
If a torque wrench is not available when in-
stalling 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.

NOTICE
Do not use any tools to remove or install
the spark plug cap, otherwise the ignition
coil coupler may be damaged. The spark
plug cap may be difficult to remove be-
cause the rubber seal on the end of the cap
fits tightly. To remove the spark plug cap,
simply twist it back and forth while pulling
it out; to install it, twist it back and forth
while pushing it in.
