HS Spark Plug Tubes Modification for MOKI radial engines

Our spark plug tubes ensure 100% secure contact with the spark plug, with easy assembly / disassembly.

The sheet-metal half-Shell has four instead of three terminal boards, thereby the plus spreads only in the lower range and
not easily over the whole length.

If fits perfectly safe and positive due to the use of Silicone with the contour cast of the spark plug. By slight pressure (spread
in the lower third) the spring ring outside of the spark plug tube takes on the Task of ground contact to the spark plug. They
do not hold the pin plug.

Easy assembly / disassembly.

No further ignition failure due to bad contacting.
