NGK spark plugs for Benelli HSR jet ski

Advice :

Replacing the spark plugs on a jetski 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-plated grease to the threads of the cylinder head in order to facilitate its re-disassembly and thus prevent the risk of spark plugs being welded to the cylinder head or broken in the spark plug well.
