Spark Plugs
4. Put the new spark plug into
the socket, then thread it into
the hole. Screw it in by hand
so you do not crossthread it.
5. Torque the spark plug. (If you
do not have a torque wrench,
tighten the spark plug
two-thirds turn after it
contacts the cylinder head.)
Tightening torque: 13 Ib-ft
(18 N.m, 1.8 kg-m).
Tighten the spark plugs carefully.
A spark plug that is too loose can
overheat and damage the engine.
Overtightening can cause damage
to the threads in the cylinder
head.
6. Install the spark plug cap.
7. Repeat this procedure for the
other three spark plugs.
