The HKS Racing Suction intake for Mazda RX-7 FD3S (13B-REW) is a vehicle-specific RS-series intake tailored to the 13B-REW rotary engine. Offered as a purpose-built replacement, it focuses on improving induction airflow and filtration for the FD3S chassis, supporting more consistent breathing and throttle response for street or track-oriented rotary setups while maintaining chassis-specific fitment.
