•Wear work clothing, including a cap, protective goggles and protective shoes during operation.
•Remove contamination including dirt and corrosion before removal, installation or disassembly.
•Keep the disassembled parts in order and protect them from dust and dirt.
•Before removal, installation or disassembly, be sure to clarify the failure. Avoid unnecessary removal, in-
stallation, disassembly and replacement.
•Be careful not to burn yourself, because each part on the vehicle is hot after running.
•Be sure to tighten fasteners including bolts and nuts to the specified torque.
•Place shop jacks or rigid racks at the specified points.
•Before disconnecting connectors of sensors or units, be sure to disconnect the ground cable from battery.

B: INSTALLATION
1. RH SIDE
Install in the reverse order of removal.
Tightening torque (Spark plug):
21 N·m (2.1 kgf-m, 15.2 ft-lb)
Tightening torque (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.
2. LH SIDE
Install in the reverse order of removal.
Tightening torque (Spark plug):
21 N·m (2.1 kgf-m, 15.2 ft-lb)
Tightening torque (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.
C: INSPECTION
Check the electrodes and inner and outer ceramic
insulator of plugs, noting the type of deposits and
the degree of electrode erosion.
1) Normal:
Brown to grayish-tan deposits and slight electrode
wear indicate correct spark plug heat range.
