A cylinder cooling system for aircraft engines is disclosed in which an air intake leads to multiple air chambers and the air is divided among the air chambers, which lead to the cylinders of the engine. In this way, approximately equal amounts of air of approximately the same temperature are able to pass over each cylinder, thereby providing more even cooling, resulting in more efficient engine performance. In addition, the cylinder cooling system is easily removable to access the engine spark plugs and fuel injectors for inspection and routine maintenance while not requiring the spark plug wiring or fuel lines to be disassembled in any way.
