Spark Plug: Specifications
SPECIFICATIONS
Spark Plug Thread Size 14, P = 1.25
Spark Plug Spark Gap 1.0 - 1.1 (0.039 - 0.043)
SPARK PLUG
RH SIDE
Tightening Torque (Spark plug): 21 Nm (2.1 kgf-m, 15 ft-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-stressing.
Tightening Torque (Ignition coil): 16 Nm (1.6 kgf-m, 12 ft-lb)
LH SIDE
Tightening Torque (Spark plug): 21 Nm (2.1 kgf-m, 15 ft-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-stressing.
