RSPANTERA High-Spec Rotor Housing for FD3S

Car Maker: Mazda
Car Model: RX7 FD3S
The area around the plug hole, where heat tends to accumulate, has been machined to increase the surface area and improve cooling efficiency. This allows for faster warm-up and cooling times, stabilizes the thermal expansion of the trochoid surface in μ units, and minimizes blow-through of the apex seal.
It has been successful in increasing power and improving fuel efficiency. *F and R versions are available, so please specify if purchasing a single item.
*Water temperature management becomes more important. Low temp is not good, use at 83°C or higher.
