Fit, Function, and Care

The Kyosho 70907 Turbo Glow Plug serves as the glow element for KE21V-series engines, supplying the single-element filament used in nitro model ignition. It is intended to fit KE21V head designs and to provide consistent ignition when correctly installed.

To install: access the head, thread the plug in by hand to avoid cross-threading, then finish with the appropriate glow-plug tool. Keep torque moderate and controlled to protect small engine threads while ensuring a firm seal.

In practical tuning terms the glow plug affects combustion at idle and during partial throttle, so test or replace plugs when you see rough idling or inconsistent running. Consistent filament condition and correct seating are key to reliable combustion behavior during use.

This item is offered as a replacement part for KE21V engine upkeep and tuning, intended for hobby model applications only.
Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How do I tell if the plug is worn?

Check the filament for thinning, breaks, or irregular glow; any signs of wear or intermittent ignition indicate it is time to replace the plug.

Are there fitment risks to be aware of?

Yes. If the thread pitch or seat shape differs from KE21V standards the plug may not seal properly; confirm compatibility before installing in non-KE21V heads.

What should I do if the engine idles poorly?

First inspect the glow plug condition and seating. If the plug looks worn or poorly seated, replace it and re-check needle settings as part of the diagnostic routine.

Is this plug suitable for competition use?

This plug is designed as a replacement component for hobby engine maintenance; evaluate its performance in your application and replace as needed based on running demands.
