Engineering Excellence
The **41-110** is the pinnacle of GM ignition technology. Iridium is one of the hardest metals on earth, allowing for a **fine-wire electrode** that requires less voltage to spark. This results in better cold starts, smoother idling, and consistent combustion under heavy loads—essential for towing and performance driving. These are the *exact* plugs your vehicle came with from the factory.
Comprehensive Fitment Guide
Pro Tip: Most V8 engines require 8 plugs. Ensure you purchase two of these 4-packs for a full tune-up.
