INSTALLATION
1. RH SIDE
Install in the reverse order of removal.
Tightening torque:
Spark plug: 21 N.m (2.1 kgf.m, 15.5 ft.lb)
Ignition coil: 16 N.m (1.6 kgf.m, 11.8 ft.lb)
NOTE:
- The tightening torque described above should be applied to only new spark plugs without oil on their threads.
- In case their threads are lubricated, the torque should be reduced by approx. 1/3 of the specified torque in order to avoid over-stressing.
