Novarossi C8TGC Conical Turbo Gold Glowplug - Off Road
Plug manufactured by Novarossi. This turbo designed plug, a
Novarossi patent, seals at the bottom of the plug instead of at
the gasket. This seal takes the threads out of the combustion
chamber volume thereby improving performance. Standard and
turbo plugs are not interchangeable. They require a Turbo Head
or UnderHead. Novarossi has discontined its C8TC model. The
only difference was in the amount of metal in the body of the plug.
Both plugs had identical coils so performance was nearly identical.
The Gold series was designed to increase performance.
