Use the wrench dimensions for a tool decision

The listing gives an 18mm working size and 160mm overall length, with a folding handle and thin-wall design. Compare those features with the plugs and access on the bike. They do not establish the correct replacement plug specification or compatibility with a nonstandard plug installation.

Keep plug service separate from electrical diagnosis

The product is a wrench for plug removal and installation. Its presence in electrical tools does not make it a meter, ignition tester or adjustment tool. Identify the actual fault or service requirement, then choose any replacement plug or diagnostic equipment independently for that task.

Common questions

Does the 18mm size identify the spark plug thread?

The tool listing uses 18mm for the wrench’s working hex. That is not a statement of spark plug thread diameter or the correct replacement plug specification. Match the wrench to the installed plug hex.

Are replacement spark plugs supplied with the wrench?

The product is listed as a tuck-away spark plug wrench. Its description does not establish a supplied plug set. Select replacement plugs separately for the engine and check their full specifications before ordering.

Can this wrench test the ignition system?

The stated function is mechanical spark plug service. It is not described as an electrical test instrument. Diagnose ignition problems with the appropriate procedure and equipment rather than treating the category label as a testing capability.
