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.

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.
