Replacement G5 Glow Plug for GGT10/GGT15 GG Series - O.S. Engine OS71655001  [OS71655001]

Fit and function: G5 plug for GGT/GG engines

This G5 glow plug is intended for O.S. Engine GGT10, GGT15 and compatible GG series model engines and is supplied as a single replacement element. It is designed to match the G5 family dimensions for use in the stated series of glow-fuel RC engines.

Fitting instructions: remove the head cover to access the plug, use the correct size glow plug socket to remove the old unit, screw in the replacement by hand to avoid cross-threading, then tighten to a snug, controlled fit as recommended by the engine manufacturer. Avoid over-tightening to prevent damage to head threads.

Operational notes: the plug forms the hot spot for ignition and plays a role in start behavior and idle stability. If the engine shows poor starting or erratic idle, inspect plug seating, electrode condition, and clip connection; a secure and correct plug fit helps maintain stable needle settings.

Precautions: confirm thread pitch and electrode condition before final assembly, work with the engine cool where feasible, and limit use to RC-scale glow gasoline engines only.
