Morphology

sparkplug + wrench

This is a straightforward noun–noun compound: 'sparkplug' (a plug related to a spark in an engine) modifies 'wrench' (a hand tool for turning). The combined meaning — a wrench specifically for spark plugs — is directly derivable from the constituents and follows regular compounding patterns, so a B1 learner who knows the parts would understand it.

Etymology

Sparkplug wrench is named from the two words sparkplug and wrench because it is a tool that fits over a spark plug deep in the engine. It lets you 'remove' or 'tighten' the plug, so the name means 'a tool to remove or tighten spark plugs'.
