O.S Engines glow plug has a slightly hotter heat range than the O.S. #8 plug. Newly developed to focus on easier running at low and medium speeds. Ideal for helicopter engines with superior performance around hovering RPM range-critical for smooth and powerful 3D and F3C type flight. Also great all around plug for most 2-stroke airplane, helicopter and car (except turbo head) engines.
