RH Side

Install in the reverse order of removal.

Tightening torque: 

Spark plug 21 N.m (2.1 kgf-m, 15.2 ft-lb) 

Ignition coil 16 N.m (1.6 kgf-m, 11.7 ft-lb) 

NOTE: 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 approx. 1/3 of the specified torque in order to avoid over-stressing.
