About the Spark Plug black outline icon
A spark plug stands vertically with its terminal nut on top, a tapered ceramic insulator with ribbed bands, a hex wrench flat in the middle and a threaded metal shell that ends in a hooked ground electrode. It signals ignition, engine tune-ups and replacement parts. Useful in auto repair booking apps, parts-store category tiles, garage service menus, vehicle maintenance checklists and mechanic training slides.
The silhouette is narrow and tall, built from stacked rectangles of varied width so each section of the plug reads at a glance, with horizontal ribs giving the shell its thread texture. It sits well next to oil can, battery, piston and wrench icons in an automotive set. Keep it at 24px or larger so the fine threads do not merge.
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.
