Product Information

The Raceworks Billet Fuel Rail Kits for Mazda 13B rotary engines are engineered to provide consistent, high-flow fuel delivery for performance street cars, track builds, and serious motorsport applications.

CNC machined from billet aluminium, these fuel rails improve internal flow and ensure even fuel distribution across all injectors, which is critical for rotary engines operating under high load, boost, and sustained RPM. Compared to factory rails, Raceworks billet rails offer superior strength, flow capacity, and reliability for modified 13B setups.

Finished in a black anodised coating, these fuel rails provide excellent corrosion resistance and a clean, professional appearance suitable for engine bays and race environments. This listing combines multiple 13B-specific fuel rail variants under one product, allowing you to select the correct option for your rotor housing and intake configuration.

Variant Fitment Guide

  • 13B S4 / S5 (ALY-019BK)
    Suits Series 4 and Series 5 13B engines, commonly found in FC RX-7 platforms using the factory-style intake and injector arrangement.

  • 13B S6–S8 (ALY-020BK)
    Designed for Series 6, 7, and 8 13B engines, typically used in FD RX-7 platforms with revised intake and injector positioning.
