NGK spark plugs for Honda brand jet skis

ref. IMR9D-9H

Advice :

Spark plugs on a jet ski should be replaced every 50 hours or every year.

For engines equipped with a compressor, it is best to carry out this operation every 25 hours or every year.

It is strongly recommended during assembly to add a thin layer of copper grease to the threads of the spark plug in order to facilitate its removal and thus prevent the risk of the spark plug being welded to the cylinder head or broken in the spark plug well.
