Novarossi Rex C7TGC Gold Series Glow Plug
C7TCG Gold Series Turbo Plug manufactured by Novarossi. This gold series 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 C7TCG 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. Gold series plugs were known for increased performance.
Quantities are limited.
