The Lycoming IO-580 engine is a horizontally opposed, six-cylinder aircraft engine featuring three cylinders per side, manufactured by Lycoming Engines.[1]
There is no carburetted version of the engine, which would have been designated O-580 and therefore the base model is the IO-580.[2]
This engine family competes with the Continental IO-550 series which are also six-cylinder engines with similar power output and weight.[3]

The IO-580 family of engines covers a range from 300 to 315 hp (224 to 235 kW). The engine has a fuel injection system which meters fuel in proportion to the induction airflow through air-bled nozzles at the individual cylinder intake ports. The engine has a displacement of 583 cubic inches (9.56 litres) and produces a maximum of 315 hp (235 kW) in its B1A version. The cylinders have air-cooled heads cast from aluminum-alloy with a fully machined combustion chamber.[1][4]
The first IO-580 was type certified on 12 August 1997 on the regulatory basis of FAR 33 effective February 1, 1965 as amended to 33-1 through 33-18. The engine is certified for use in either tractor or pusher configuration installations.[2]
