MAINTENANCE
If the spark plug is dirty, clean the spark plug using a
spark plug cleaner.
Visually inspect the spark plugs. Discard the plugs if the
insulators (1) are cracked, chipped, or fouled.
Measure the plug gap between the center electrode (2)
and side electrode (3) with a wire-type feeler gauge.
SPARK PLUG GAP:
1.00 – 1.10 mm (0.039 – 0.043 in)
RECOMMENDED SPARK PLUG:
ZFR6K-11 (NGK)
KJ20DR–M11 (DENSO)
Adjust the spark plug gap by bending the side
electrode, if the gap is out of specification.
Make sure each sealing washer (4) is in good condition
and replace the spark plug if necessary.
Thread the spark plugs in by hand to seat the sealing
washers and prevent cross-threading.
A loose spark plug can become very hot and can
damage the engine. Overtightening the spark plugs can
damage the threads in the engine.
Tighten the spark plugs to the specified torque.
TORQUE: 18 N·m (1.8 kgf·m, 13 lbf·ft)
Install the ignition coils and tighten the socket bolts to
the specified torque.
TORQUE: 12 N·m (1.2 kgf·m, 9 lbf·ft)
Connect the 3P connector to the ignition coil.
Install the plug hole coil cover and tighten the two bolts.
Attach the upper side of the under cover grommet (1)
and install the two mud guard clips (2).
After installing the clips, make sure that the lip (3)
behind the under cover grommet is securely installed
on the L./R. engine under covers.
Install the engine cover.
