NGK spark plugs for Honda jet skis

NGK spark plugs for Honda brand jet skis

ref. IMR9D-9H

Advice :

Replacing the spark plugs on a jet ski should be done every 50 hours or every year.

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

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