Tightening torque (Spark plug):
21 N-m (2.1 kgf-m, 15 ft-lb)
Tightening torque (Ignition coil):
16 N.m (1.63 kgf-m, 11.8 fi-lb)
CAUTION:
The above torque should be only applied to
new spark plugs without oil on their threads.
In case their threads are lubricated, the torque
should be reduced by approximately 1/3 of the
specified torque in order to avoid over-stress-
ing.
