Hyper-Tuning Set

A "Hyper Tuning Set" that allows for increased output by replacing the piston and camshaft without changing the displacement.
This is a great value set that includes a high-compression piston kit, a sport camshaft, FI-CON2 (injection controller), and a spark plug.
The high-compression piston cannot be used alone.
Simultaneous installation of a Takegawa sport camshaft and spark plug (equivalent to CR8E) is required.
This product requires high-octane gasoline.
Regular gasoline cannot be used.
