AC Spark Plug MR43LTS (Sold Individually)
The MR43LTS is the small block Chevy day-one ride-or-die. Copper-core, extended tip, and made to keep your old-school V8 purring—or growling, if you’re doing it right. Whether it’s a stock rebuild or a street bruiser, this plug’s been there, gapped that.
Factory fit, no-fuss fire, GM-approved. Add to cart and keep that bowtie lit.
