The O.S. Engine OSMG2693 #10 A5 glow plug provides reliable ignition for model aircraft using .60 cu in (9.8cc) and larger engines. Its medium-cold heat rating helps maintain consistent combustion across a range of throttle settings, making it a solid choice for club flyers and competition pilots who need predictable starts and smooth running.
This medium-cold plug strikes a balance between preventing fouling and supporting good idle and acceleration. It is built to cope with the demands of larger glow engines, helping improve engine stability without aggressive tuning changes.
