Autolite Spark Plug 104 (Sold Individually)
The blue-collar hero of spark plugs. The Autolite 104 is your go-to for small blocks, daily beaters, and classic V8s that just want to run right. Copper core, standard heat range, and built to take a beating without getting fussy.
It’s the plug your dad used—and probably still does. Gap it, twist it, fire it. Add to cart and keep that old-school fire alive.
