The EF is an automotive engine made by Subaru, introduced in 1984 for the Subaru Justy. It is a water-cooled, straight-three, four-stroke engine with a belt-driven single overhead camshaft, and a chain-driven balance shaft. It has an alloy cylinder head and a closed deck iron engine block with a bore spacing of Script error: No such module "convert".. The two-cylinder EK23 engine is closely related to the EF series, sharing the same bore spacing and overall design.[1] The export market 665 cc EK42 motor even shares the bore and stroke of the EF10.

It is the first Subaru engine to incorporate the displacement in its name, and the only iron block Subaru ever.
