Wagner Tuning BMW S58 EVO1 Intake Manifold Fuel Rail Hose Kit

The Wagner Tuning S58 EVO1 Intake Manifold + Fuel Rail + Hose Kit is a complete high-performance upgrade engineered for BMW models running the S58 engine.
Designed to replace the restrictive OEM plastic manifold, the EVO1 features a larger, more efficient aluminium plenum, revised runners and full multi-port injection (MPI) compatibility — providing the airflow and fuelling headroom required for high-boost, hybrid-turbo and ethanol-powered S58 builds.

With the included billet fuel rail and hose kit, this package delivers a ready-to-integrate MPI solution for serious performance applications.

Key Features

• Large, high-flow aluminium plenum for increased charge volume

• Optimised runner geometry for improved cylinder filling and top-end power

• Significantly reduced pressure drop vs OEM manifold

• Billet aluminium fuel rail included

• Reinforced hose kit included for MPI integration

• Supports high-boost, hybrid turbo and ethanol (E30–E85) tuning

• Integrated MPI injector ports (injectors not included unless specified)

• Direct-fit design with OEM sensor compatibility

• TIG-welded motorsport-grade construction

• Ideal for track, drag and high-output fast-road S58 builds

Compatibility

BMW S58 Models

• G80 / G81 – M3

• G82 / G83 – M4

• F97 – X3 M / X3 M Competition

• F98 – X4 M / X4 M Competition

(Fits all S58 engines across G8X and X3M/X4M platforms.)

Ideal For

• High-boost Stage 2+, hybrid turbo and big-power S58 builds

• Cars running ethanol blends requiring additional fuelling headroom

• Drivers needing improved charge airflow and cylinder balance

• Track, drag and roll-racing applications demanding high thermal stability

• Builds planning to run MPI alongside OEM direct injection

Why Choose the Wagner Tuning S58 EVO1 Intake Manifold + Fuel Rail + Hose Kit

The stock S58 intake manifold becomes restrictive when power levels increase, particularly at higher boost or when using ethanol fuels. Wagner’s EVO1 solves these issues with a significantly larger plenum, smoother internal geometry and far stronger construction — ensuring improved airflow stability, reduced pressure drop and consistent power delivery.

The included billet fuel rail and hose kit enable safe, reliable multi-port injection — essential for high-power S58 tuning where the factory direct-injection system alone cannot meet fuelling demand.

With proven Wagner engineering, motorsport-grade materials and precise OEM fitment, this is one of the most capable intake/fuelling upgrades available for the S58 platform.

Installing / Notes

• MPI injectors and controller not included

• ECU calibration required to enable MPI fuelling

• Professional installation recommended

• Works with OEM or aftermarket intercoolers and charge pipes

• Coolant/fuel system bleeding required after installation
