The O.S. Engine P3 Turbo Ultra Hot Glow Plug, identified by model number OSMG2699, is engineered to optimize the performance of turbo head racing engines from .18 to .28 cubic inches (2.9 to 4.6 cc). Its ultra-hot heat range supports stronger ignition at low RPM and promotes smoother acceleration and improved torque during throttle openings.
Built to seat in the inner head of turbo-type cylinder heads, the P3 glow plug helps with easier starting and steadier idle behaviour, especially when running 20% nitro fuel. This combination of reliable low-speed running and added torque makes it a practical choice for racers and hobbyists moving up to turbo engines.
