The Subaru EK was an inline twin-cylinder engine used in most Subaru kei cars from 1958 until 1989. Early versions were air-cooled two-stroke engines, which were replaced by water-cooled configurations in 1971. In 1973 the engine was upgraded to a four-stroke single-overhead-cam design with an alloy block and head, fitted with the SEEC emissions system, later SEEC-T, to meet Japanese government emission regulations. Among the cars it powered was the 1969 to 1972 Subaru R-2, and it was succeeded by the four-cylinder EN series from 1989. The three-cylinder EF engine was closely related to the later two-cylinder EK23, sharing its bore spacing and overall design.
