Radium Engineering Secondary Fuel Rail for 1993-1995 Mazda RX-7 (13B-RE) 20-0446
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 1993-1995 Mazda RX-7 models (13B-RE engine conversions).
The Radium Engineering high-flow secondary fuel rail is designed specifically for the 13B-RE rotary engine, originally found in the 1990-1995 Mazda/Eunos Cosmo. This rail is CNC-machined from aluminum and features a large internal bore to support the high-volume fuel demands of performance-built rotary engines. Like the factory secondary rail, it is designed with 11mm injector bores to permit the use of OEM fuel injectors or equivalent upgrades.
To ensure long-term reliability and compatibility with modern fuels, the rail is finished in a type II black anodized coating. This provides a durable barrier against corrosion and makes it fully compatible with all popular fuel types, including E85.
- Large internal bore reduces pressure drops and supports high-horsepower builds
- 11mm injector bores compatible with OEM-spec injectors
- Type II black anodized finish for E85 and alcohol fuel compatibility
- Direct fit for the 13B-RE secondary intake manifold
- Manufacturer Part Number: 20-0446
