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 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.
