1978 Honda CB750A · Spark plug wrench Buying guide

Check plug size and access together

The wrench listing gives an 18mm socket size and 160mm overall length. Those details help assess access, but the wrench does not select the correct spark plug specification for you.

Select the wrench by the installed plug

Check what is fitted before ordering, especially if the ignition or plugs have been changed during earlier repairs. The listed 18mm size concerns the tool’s engagement with the plug. Use the spark plug description separately to check the replacement plug you intend to install.

Allow room to use the handle

Overall length and socket-wall shape both matter when access is restricted. Compare the wrench photograph and 160mm length with the space around your plugs. The handle tucks into the socket for storage; that feature does not establish clearance in every modified engine layout.

Common questions

What does the 18mm measurement refer to?

It is the listed wrench size for engaging the spark plug. It does not establish the plug’s thread size or other specifications. Compare the fitted plug and check the separate spark plug listing when choosing a replacement.

How long is the wrench?

The listing gives a 160mm overall length and describes a thin-wall design for deep plug holes. Compare that size with the available access on your motorcycle; altered components around the engine can affect the room available.

Does this tool diagnose an ignition fault?

This product is a spark plug wrench for removal and fitting work. The listing does not identify it as an electrical tester. If you are investigating an ignition fault, choose the diagnostic equipment required by your service procedure separately.
