standard spark
IMR9D-9H (NGK)
plug
Use only the recommended type of spark
plugs in the recommended heat range. It
should not be necessary to use spark plugs in
a different heat range because the engine is
water-cooled.

range can cause engine damage.

Servicing Your Honda
This PWC uses spark plugs that have an
iridium coated center electrode. Be sure to
observe the following when servicing the

spark plugs.

• Do not clean the spark plugs. If an
electrode is contaminated with accumulated
objects or dirt, replace the spark plug with a
new one.
• To check the spark plug gap, use only a
"wire-type feeler gauge".
To prevent damaging the iridium coating of
the center electrode, never use a "leaf-type
feeler gauge."
• Do not adjust the spark plug gap. If the gap
is out of specification, replace the spark
plug with a new one.
