The BMW M337 is a straight-6 OHV piston engine which replaced the BMW M78 and was produced from 1952-1958.
Built to power BMW's first new car after the Second World War, the M337 engine was a significant update of the M78. The cylinder head was revised, the inlet manifold was a new design, and a reinforced crankshaft with bigger, more modern bearings was used.
