1981 Honda CB750F · Spark plug service tool Buying guide

Match the socket to the plug before checking access

The 18mm figure describes the wrench, while 160mm is its overall length. Compare those tool measurements with the installed plug and surrounding components; choosing a wrench does not determine the replacement plug’s specification.

Parts to consider

Honda CB1100/CB1000/CB900/CB750 Spark Plug Wrench 18mm wrench with tuck-away handleThin-wall spark plug tool, 160mm overall. The handle tucks into the socket for storage; compare access around your plugs.View part

Wrench size and plug specification answer different questions

A socket that engages the hex does not establish the spark plug’s thread, reach or ignition requirements. Compare the plug being removed with the replacement plug listing separately. Use the tool’s 18mm size to decide whether this wrench matches the hex you will work on.

Allow working room as well as storage space

The handle stores inside the socket, but service access still depends on the parts surrounding the plug. Compare the thin-wall tool photograph and overall length with the installed engine layout. If components have been changed, assess that arrangement before deciding the wrench will reach the plug.

Common questions

Does 18mm describe the spark plug thread?

Here it is the listed wrench size for engaging the plug hex. The tool listing does not select a plug thread or reach. Identify replacement plug requirements from the plug and ignition information, then choose a wrench that fits its hex.

What does the tuck-away feature do?

The product description says the handle tucks into the socket. That helps identify how the tool stores, without establishing working clearance on every motorcycle. Compare its 160mm overall length and socket shape with the space available at your plugs.

Is this an ignition diagnostic tool?

This item is a spark plug wrench, not a listed tester or fault-finding instrument. Choose it for access to the fitted plug hex. An ignition investigation needs the diagnostic equipment and procedure appropriate to the actual ignition system.
