Powering American aircraft, then just in its infancy, from Charles Lindbergh's Spirit of St. Louis in the 1920s to Amelia Earhart's solo transatlantic flight in the 1930s, AC Delco spark plugs were at the forefront of technology and innovation.
Having merged with General Motors, AC Spark Plug (formerly known as Dayton Engineering Laboratories Company (DELCO), the companies went to work for the Allied cause during World War II, producing DELCO batteries for Navy planes.
It wasn't until the 1980s when AC Delco found its true fit with GM, ensuring that parts fit exactly like true OEM General Motors parts.
AC Delco is the true GM Original Equipment parts brand. Known primarily for their automotive brands -- Chevrolet, Buick, GMC, and Cadillac -- GM also makes marine replacement spark plugs for popular engines like Mercruiser and Crusader, which we stock and ship.
Today, the AC Delco brand is known around the globe including North America, Africa, Japan, and India.
