Glow Plug Fitment and Use

The Kyosho 70907 Turbo Glow Plug is supplied as a single-element ignition part for the KE21V engine range. It acts as the primary glow filament for small nitro engines and is made to suit KE21V head profiles.

Fitting should be carried out by hobbyists familiar with nitro engines: remove the head access, start the glow plug by hand to prevent cross-threading, then secure with the correct wrench. Tighten only to a light, controlled torque appropriate for tiny engine threads to avoid damage.

When tuning, the choice and condition of the glow plug will influence idle and part-throttle combustion, so swap plugs if you notice unstable idle or poor throttle response. Routine checks of filament condition and seating will help maintain steady combustion during runs.

Offered as a replacement part for KE21V engine servicing and tuning, this glow plug is intended for model hobby use.
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.

Is thread size standard for other engines?

The 70907 is specified for KE21V; verify the thread and seat dimensions of other engines before fitting to ensure correct compatibility.

How tight should I torque the plug?

Use a light, controlled torque—enough for a good seal but not so much as to risk stripping the small threads. Hand-start then finalise with a glow-plug wrench.

Will changing the plug alter tuning?

Yes. Different plug condition or heat characteristics can change ignition timing behavior at idle and part-throttle, so consider plug condition when tuning.

What inspection routine do you recommend?

Inspect the filament for breakage and the seating for secure contact before each run; replace the plug if combustion becomes erratic or after heavy use.
