Give your GM truck or SUV a tune-up with this complete set of 8 high-performance ignition coils. This ACS brand set is designed as a direct replacement for models using the common UF413 coil (OEM numbers 12570616, 12611424, etc.). It fits many Chevrolet Silverados, GMC Sierras, Cadillac Escalades, and other GM vehicles with specific V8 engines. The seller claims these coils offer a 15% increase in performance and energy over stock, which can translate to smoother running, better throttle response, and maybe even a slight MPG improvement. They come with a LIFETIME manufacturer warranty, which is fantastic. If you're experiencing a rough idle, misfires, or just have high mileage on your original coils, replacing all eight at once is a proactive move. Installation is usually easy – they're right on top of the engine, just unplug the old one, unscrew it, and swap in the new. The UPC is 7423028381365. A quality upgrade or maintenance item for any GM truck owner who wants reliable spark.
