ACDelco GM Original Equipment parts, including the spark plugs, may have been sold as ACDelco Professional. The product is made from 100% pure copper and has a life expectancy of over 25 years. It comes with a lifetime warranty against defects in materials and workmanship. Notably, the original equipment was manufactured by General Electric Company (GE) in 1932. The products are now being sold at a reduced price.
GM Genuine Parts are designed, engineered, and tested to rigorous standards to help promote proper and safe repair of vehicles. The parts are manufactured by General Motors in collaboration with the manufacturer’s engineering department. These parts have been approved by the National Highway Traffic Safety Administration (NHTSA) for use in collision repairs. They are also certified by the NHTSA for safety reasons. Notably, there is no shortage of GM Genuine Parts.
Iridium allows for smaller, more efficient electrode designs for improved cold starting and quicker acceleration
Suppressor seal meters spark energy for longer electrode life and seals against combustion leakage. Before installing new spark plugs, use a gap guide to make sure your new spark plugs have the correct gap
One piece suppressor seal blocks radio frequencies that can affect vehicle electronics
Iridium offers better engine idle stability and smoother performance
Iridium fine-wire electrode helps improve ignition of the fuel and burns away carbon deposits on the tip of the plug as they form, to help improve fuel economy
Some ACDelco GM Original Equipment parts may have formerly appeared as ACDelco Professional
One-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 life
Pure copper core results in cooler electrode temperature for maximized durability and fouling resistance
Double platinum point pad on center and ground electrode offer excellent durability and consistent voltage demands to help reduce wear on ignition system
Four yttrium enhanced ground electrodes resist spark plug wear and oxidation for exceptional performance life
Revolutionary surface air gap firing technology featuring Bosch’s unique four ground electrode design delivers the most powerful spark for the most efficient combustion and optimum horsepower without increasing the voltage requirement
Fused iridium and platinum center electrode, sintered into an extended insulator nose results in reaching self-cleaning temperature only seconds after starting and provides exceptional wear resistance
Factory pre-set gap allows for easy installation that never requires adjustment
Fusion’s voltage requirement increases less over time versus other iridium plugs for longer reliable performance of the vehicle’s ignition system
