1982 Honda CB750SC · Spark Plug Tool Buying guide
The wrench is specified for 18mm spark plugs and measures 160mm overall. Its tuck-away handle helps storage, while the thin wall is intended for the deep plug access found on compatible CB engines.
The 18mm wrench size refers to the plug hex it engages, not the thread diameter. Confirm the plug actually installed and the access around it. A replacement cap or altered nearby component can affect room even when the plug designation is correct.
This product is a removal and fitting tool with a tuck-away handle. It is not a spark tester, electrical meter or gap gauge. Use the appropriate equipment and service instructions for any diagnosis or measurement planned alongside routine plug replacement.
Here it is the wrench’s working size for the plug hex. Identify the fitted plug and its hex before choosing a tool; do not use socket size to infer plug-thread specification.
The listed overall length is 160mm. Compare that with the access available around the fitted head and plug caps before choosing it for the motorcycle’s service kit.
Its thin-wall design is intended for deep CB plug access. Compare the 18mm hex and 160mm overall tool length with the actual head and caps, especially where nearby parts have been changed.
