This is a replacement turbo head button for the Novarossi P5, P5X and Plus 21-5 off-road buggy engines. This is for Turbo plugs, not Standard plugs. Most P5 engines come with standard plug button heads, so this can be used to update your engine to use a Turbo plug for more power. This will work with any Novarossi brand engine including the Top and Rex lines.
