As with normal spark plugs, install
spark plugs using the
correct procedure and appropriate torque.
Q

A
spark plugs use a ultra-fine 0.4 mm iridium
center electrode and the spark gap is already set at the optimum
distance.
If the electrode is damaged by gap adjustment or cleaning, the spark
plugs will not perform to their best.
Do not adjust the spark plug gap.
Use of a spark plug cleaner for short periods is
acceptable if low pressure is used.

Notes for Installing and Removing
Spark Plugs
1
Use a spark plug wrench to suit the hexagonal part of the spark plug to ensure that no burring occurs.
2
When removing the spark plug, ensure that no fouling, such as oil on the outside of the plug, enters inside the engine.
3
When installing
spark plugs, clean the seat for the spark plug in the
engine, check the gasket,and then mount the plugs on their seats.
4
Place the plugs in vertically and
screw in by hand until tight.
6
Do not over-tighten spark plugs as this may damage the engine (in particular, aluminum engines)
and cause fracturing of the thread.
5
Then, using a spark plug wrench, rotate for
between 1/4 and 1/2 of a turn (or between 1/5
and 1/4 of a turn when they are to be re-used).
Is there anything I need to be aware of
when fitting
?
Can the
gap be
adjusted? Can I use any spark plug cleaners
with the
?
