O.S. Engine OS71655001 G5 Glow Gasoline Plug for GGT10 GGT15 GG Series  [OS71655001]

G5 glow plug for GGT/GG series

This is an RC-scale G5 glow gasoline plug intended for use with O.S. Engine GGT10, GGT15 and compatible GG series model engines. It serves as the replacement glow plug element for glow-fuel powered RC engines and is supplied as a single plug component (pcs). The item is designed to match the G5 family naming and to be used only on model engines in the stated series.

Installation is straightforward: remove the engine’s head access, carefully extract the old plug with the correct spark plug wrench, hand-thread the replacement to avoid cross-threading, then torque to the engine maker’s recommended tightness. Use a proper glow plug socket or wrench sized for the plug, and avoid over-tightening to prevent damage to the engine head.

Role in tuning: the plug provides the hot point for ignition and affects cold-start reliability and idle stability on glow gasoline setups. When diagnosing running issues, verify plug condition, seating, and connection to the ignition clip; a consistent, correct plug fit supports predictable needle adjustments and throttle response.

Notes and precautions: confirm thread fit and center electrode condition before final assembly, always work on the engine cool where possible, and keep this part confined to RC-scale glow gasoline engines only.
