Today ACDelco products are chosen the world over, an accomplishment only the past can explain. So buckle up and join us for a fast ride back in time.
How It All Started


Albert Champion bids adieu to France and hits the high seas for America. Albert was a champion bicycle racer, and he used the draft from speedy motorcycles to help him train and set a pace. Once in Boston, Albert makes his own spark plugs and sells them to friends for extra cash. With the help of investors, Albert turns his hobby into a business, The Champion Ignition Co.

Brothers Frank and Perry Remy founded the Remy Electric Co. The Brothers Remy were the first to build dynamos and magnetos, which were used instead of batteries for ignition in early vehicles.

The honeymoon ends between Albert Champion and his investors. The investors pull out of the deal and keep the Champion name. (Ouch.)

Albert Champion, still the competitor, joins forces with Buick Motor Co. The two make beautiful spark plugs together for the AC Spark Plug Division. Guess where they got the name.

Here comes The General. United Motors Corp (UMC). is formed by Alfred P. Sloan – the man who would eventually become president and then chairman of GM. UMC eventually absorbs Buick and AC Spark Plug, and later merges with Chevrolet to form General Motors. That same year, UMC forms United Motors Service Inc. (UMS), to sell and service parts made by the company.

Remy Electric, which had been bought out twice since being formed by the Remy brothers, merges with competitor Dayton Engineering Labs Co. (Delco) to form Delco Remy Corp.
Airplanes To Rockets

Off we go, into the wild blue yonder. AC Spark Plugs are used in Charles A. Lindbergh’s transatlantic flight.

General Motors Parts Division (GMPD) forms in order to consolidate the automaker’s parts-marketing activities.

C igniter plugs are used to fire the second- and third-stage rocket engines that propel Neil Armstrong, Mike Collins and Buzz Aldrin to the moon. That same year, GMPD becomes a separate business unit. It distributes replacement parts to GM dealers.

United Motors Service is renamed United Delco Division.


Guess what? That’s right, it’s time for another merger. The AC-Delco Division is born with the combination of the United Delco and AC Spark Plug sales organizations.
