Description

ACDelco GM Original Equipment Double Platinum Spark Plugs are designed, engineered, and tested to rigorous standards, and are backed by General Motors. With a copper core and double platinum pads on the center electrode, these plugs are designed to deliver long-lasting performance. ACDelco GM Original Equipment parts are the true OE parts installed during the production or validated by General Motors for GM vehicles. Some ACDelco GM Original Equipment parts may have formerly appeared as GM Genuine Parts (OE) or ACDelco Professional.ACDelco GM Original Equipment parts are designed, engineered and tested to rigorous standards, and are backed by General MotorsDouble platinum point pad on center and ground electrode offer excellent durability and consistent voltage demands to help reduce wear on ignition systemGM Engineers design and validate OE parts specifically for your Chevrolet, Buick, GMC, or Cadillac vehicleGM regularly updates production and service part designs to integrate new materials and technologiesOne-piece, fired-in suppressor seal blends three glass types for a gas-tight seal that helps reduce radio frequency and engine interference, regulate spark plug energy, and protect against compression pressures for long lifeSome ACDelco GM Original Equipment parts may have formerly appeared as GM Genuine Parts (OE) or ACDelco ProfessionalPure copper core results in cooler electrode temperature for maximized durability and fouling resistance
