Cox .049 -.051 Glow Plug Adapter with Extra Cooling (5 Fin)

Cox .049 -.051 Glow Plug Adapter with Extra Cooling (5 Fin).

A 5 fin conversion that has superior cooling and consists of one clamping ring and one "medium hot" glowplug insert, this saves having to buy complete heads if the glow element burns out (see related items for replacement inserts). This conversion maintains full RPM as per the original head and is suitable for all Cox .049-.051 engines.

Please note:
 When using this head conversion there is a possibility that the engine may have too much compression and will not run properly. If this is the case then we recommend adding up to 3 extra head gaskets, then experiment removing one at a time until the engine operates smoothly and with optimum power.
