Mr. Gasket was founded in 1964 by drag racer Joe Hrudka. Hrudka established the company which aims to be a primary source for racers in their need for head gaskets, exhaust gaskets, oil pan gaskets, and fasteners. This is one of Hrudka's tactics to make a name for himself and the company at Cleveland-area tracks, Nowalk and Dragway 42. Mr. Gasket continues to expand application coverage as it introduces more new products intended for race cars and muscle cars. Aside from gaskets responsible for its current established status, it offers other high performing parts, including fuel additives and carburetors. Mr. Gasket is also an important part of Holley Performance, a leader in fuel systems for over 100 years. Holley Performance products include performance fuel pumps, intake manifolds, and engine dress, race and marine applications.
