Wagner Tuning BMW/Toyota B58 EVO1 Intake Manifold Fuel Rail
This Wagner Tuning fuel rail is purpose-built to work with the EVO1 Intake Manifold and Intercooler system for the BMW and Toyota B58 engine. It provides a reliable, high-flow fuel supply path for tuners and builders running upgraded injectors, helping the engine cope with increased fuelling demands at higher power levels.
The rail is CNC-machined from billet aluminium for strength and consistent fuel delivery, and is designed to fit cleanly alongside the Wagner Tuning EVO1 manifold without requiring custom fabrication.
Key Features
- Designed specifically for use with Bosch EV14 xT Compact injectors with extension (part numbers 0280.158.038 or 0280.158.040)
- Two ORB-8 3/4×16 ports for flexible fuel line routing
- Direct fitment with the Wagner Tuning EVO1 B58 Intake Manifold
- Supplied unassembled, ready to be built into your fuel system
Why Upgrade the Fuel Rail?
When fitting larger injectors and pushing the B58 beyond standard outputs, the OEM fuel rail can become a limiting factor. A larger volume rail helps maintain steady fuel pressure across all cylinders, which supports cleaner running and more consistent power delivery during heavy load.
Important Fitment Information
This fuel rail is only compatible with the original Wagner Tuning EVO1 Intercooler/Intake Manifold setup. It will not fit the OEM manifold or other aftermarket manifolds.
Injector compatibility is restricted to the Bosch EV14 xT Compact with Extension (0280.158.038 or 0280.158.040). Other injector lengths or styles will not seal correctly.
