Who is ACDelco?
ACDelco is a subsidiary of GM. They are 100% owned and operated by GM, but they operate under a separate brand name for historical reasons
Basically, once upon a time (early 1900s), AC and Delco were two separate companies that supplied various parts to General Motors. AC provided Champion brand spark plugs, while Delco was a large company manufacturing a variety of parts. AC's Champion brand spark plugs were used in Charles Lindburgh's Spirit of St. Louis (which was the first plane to cross the Atlantic on a single tank of fuel). Champion plugs became a household brand name, and Buick eventually acquired AC.
Meanwhile, Delco continued to grow into a large supplier and was eventually acquired by GM. However, it wasn't until the 1970s that GM merged Delco with Buick-owned AC, forming a new company ACDelco. ACDelco then became GM's official parts supplier.
