Wagner Tuning BMW S58 EVO1 Intake Manifold Fuel Rail
Wagner Tuning’s dedicated fuel rail is engineered specifically for the BMW S58 engine when paired with their EVO1 intake manifold and integrated intercooler system. It provides a reliable, high-flow fuel delivery solution for tuners running larger injectors and pushing well beyond standard power figures.
Machined to suit Bosch EV14 xT Compact injectors with extension (part numbers 0280.158.038 or 0280.158.040), this rail ensures consistent fuel pressure and accurate atomisation across all six cylinders. Two ORB-8 3/4×16 ports give plumbing flexibility for custom fuel system builds, including return-style setups, surge tanks, or upgraded fuel pumps.
Why fit a dedicated fuel rail?
On heavily tuned S58 engines, the standard fuel system can become a limiting factor. A purpose-built rail with larger injector bores and proper porting helps maintain stable pressure under high demand, supporting bigger power, cleaner combustion, and a more consistent tune.
- Designed for Bosch EV14 xT Compact injectors with extension (0280.158.038 / 0280.158.040)
- Two ORB-8 3/4×16 ports for flexible fuel system plumbing
