The HKS Super Air Filter for Mazda RX-7 FC3S/FD3S 13B-REW is a high-performance, durable air filter engineered to deliver superior airflow compared to standard paper filters. Designed specifically for the 13B-REW rotary engine, this filter optimizes air intake, improving throttle response, increasing power potential, and enhancing overall engine performance while maintaining reliable protection against dust and debris.

Featuring high-flow, dry-weave, multi-density polyester mesh, the HKS Super Air Filter allows your engine to breathe more freely. Reduced air restriction results in improved combustion efficiency, more power, and smoother, more responsive acceleration.

Progressively denser layers trap dust at multiple depths, preventing premature clogging and ensuring consistent airflow over time. This innovative structure extends the filter’s lifespan while keeping your engine running at peak performance.

The HKS Super Air Filter for Mazda RX-7 FC3S/FD3S 13B-REW is easy to install and designed to replace the factory air filter without modifications.
