About the Spark Plug black outline icon
A spark plug stands upright inside a thin circle, showing the small terminal nut on top, a tapered ceramic insulator, the wide hex collar in the middle, the ribbed threaded shell and the hooked ground electrode at the base. It signals ignition, tune-ups and engine maintenance. Use it in auto parts stores, garage and mechanic websites, vehicle service checklists, car diagnostics apps and motorsport graphics.
The part is drawn symmetrically along a vertical axis, with the hex collar as the widest band splitting the slim upper insulator from the banded lower shell. The enclosing ring matches other badge-style automotive icons. Pair it with oil can, battery, piston and wrench marks, and size it at 32 px or more so the thread bands stay separate.
This is the black outline version of the spark plug icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
