Autolite Racing Spark Plug AR-73 (Sold Individually)

The Autolite AR73 is the unsung hero of high-RPM chaos. Non-resistor, cold-range, short-reach copper-core goodness built for race fuel, tight gaps, and no apologies. It’s what you slap into your engine when you’re tired of misfires and ready for mayhem.

Track it, gap it, gap your buddies. Add to cart and let your ignition do the trash talkin’.
