Spark Plugs
For nickel spark plugs (traditional type):
You should inspect spark plugs periodically
for carbon deposits. When carbon accu-
mulates on a spark plug, a strong spark
may not be produced. Remove carbon
deposits with a wire or pin and adjust the
spark plug gap.

NOTICE
When pulling out the ignition coils,
do not pull on the cable. Pulling on
the cable can damage it.
NOTICE
• When installing the spark plugs,
screw them in with your fingers to
avoid stripping the threads.
Tighten the spark plugs with a
torque wrench to 17.5 Nm (1.8 kg-
m, 13.0 lb-ft). Do not allow contami-
nants to enter the engine through
the spark plug holes when the
plugs are removed.
• Never use spark plugs with the
wrong thread size.
