Top Fuel S660 Combustion chamber processed cylinder head

The stock combustion chamber is designed with low-speed torque and fuel efficiency in town riding in mind, but this combustion chamber shape is useless when it comes to promoting high power.
This product is a cylinder head that has undergone machining processing on the genuine cylinder head and has been processed into a combustion chamber shape that emphasizes high boost and high power.
Since the compression ratio is slightly lowered on the premise of applying high boost, it is not suitable for engines with low boost specifications, and the torque in the low speed range where boost is not applied and the fuel efficiency performance in city riding will also decrease.
Parts for high-tuned competition vehicles.
