Wagner Tuning BMW S58 EVO1 Intake Manifold Fuel Rail

The Wagner Tuning S58 EVO1 Intake Manifold + Fuel Rail is a high-performance upgrade designed to replace the restrictive OEM plastic manifold used on BMW’s S58 engine.
Featuring a significantly enlarged aluminium plenum, optimised runners and full multi-port injection (MPI) compatibility, the EVO1 provides the airflow stability and fuelling overhead required for high-boost, hybrid-turbo and ethanol-powered S58 builds.

Supplied with a high-flow billet aluminium fuel rail, this package is the ideal foundation for any serious performance setup.

Key Features

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

• Optimised runner geometry for improved cylinder distribution and top-end efficiency

• Reduced pressure drop compared with the factory intake manifold

• Billet aluminium fuel rail included (MPI-ready)

• Integrated MPI injector ports (injectors/lines/controller not included)

• Strong TIG-welded construction for high-boost reliability

• Direct-fit design retaining all OEM sensors and connections

• Suitable for ethanol blends (E30–E85) and advanced fuelling strategies

• Supports hybrid turbo and big-power S58 applications

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-powered BMW platforms.)

Ideal For

• Stage 2+, hybrid turbo and high-power S58 builds

• Cars running ethanol blends that require increased fuelling capability

• Drivers needing improved airflow stability at higher boost levels

• Track, drag and roll-racing S58 applications

• Builds planning to integrate MPI alongside factory direct injection

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

The stock S58 intake manifold is restrictive at higher boost, limiting top-end flow and cylinder balance. Wagner’s EVO1 replaces this weak point with a stronger, larger, and more efficient aluminium design that ensures consistent airflow even under demanding conditions.

The included billet fuel rail provides essential headroom for MPI — a must for hybrid turbos, ethanol blends and big-power tuning where the stock DI system alone becomes insufficient.

With premium materials, precise fitment and proven cooling and airflow improvements, the EVO1 manifold is one of the most capable and trusted intake upgrades for the S58 engine.

Installing / Notes

• MPI injectors, lines and controller not included

• ECU calibration required when enabling MPI

• Professional installation recommended

• Compatible with OEM or upgraded intercooler/charge pipe systems

• Fuel and coolant system bleeding may be required
