Holley Inc.
A maker of high-performance automotive parts for car enthusiasts, Holley designs and sells fuel, exhaust, ignition, and safety gear through brands like Holley EFI, MSD, Flowmaster, and Simpson, offering them directly to consumers and through distribution partners. Brothers George and Earl Holley started the company in Bradford, Pennsylvania, and after an 1901 trip to Paris they licensed a French carburetor design that became famous as the "Iron Pot" — a part that powered early Ford Model Ts and Oldsmobiles.
