The Avia M 332 (originally known as the Walter M332) is an air-cooled four-cylinder inverted inline engine. It was designed by Bohumil Šimůnek, of Motorlet Walter Aircraft Engines, as a more powerful replacement for the four-cylinder Walter Minor engine, going into production in 1958. Piston aircraft engine production was transferred from Walter to Avia in 1964, the engine becoming the Avia M 332.
