Kyosho 70907 - Turbo Glow Plug (KE21V) glow plug for KE21V RC engines  [KY-70907]

Turbo Glow Plug for KE21V Engine

This Kyosho 70907 Turbo Glow Plug is an RC-scale glow plug intended for use with the KE21V engine family. It serves as the ignition element for nitro RC engines and is specified for compatibility with KE21V-design heads. The component is described as a turbo-style glow plug, with the name indicating its match to the KE21V engine.

Installation is straightforward for model builders familiar with nitro engines: remove the engine head access, fit the glow plug by hand to avoid cross-threading, then final-tighten with the correct glow plug wrench. Use moderate torque appropriate for small engine threads to secure the plug without over-tightening.

In tuning terms the glow plug affects ignition behavior at idle and part-throttle, so replace or test plugs when odd idle, inconsistent running, or starting difficulty appears. Routine inspection of the filament and proper seating in the head help maintain consistent combustion characteristics during setup and track use.

As an RC engine spare part, this glow plug is a direct replacement component for KE21V engine maintenance and tuning tasks, intended for hobby model use only.
