The Wagner Tuning S58 EVO1 Intake Manifold + Fuel Rail Kit is a high-performance upgrade designed to unlock greater airflow, improved cylinder balance and increased fuelling capability for BMW’s S58 engine.
Replacing the restrictive OEM plastic manifold, the EVO1 features a significantly enlarged aluminium plenum, optimised runners and full multi-port injection (MPI) readiness — giving high-power S58 builds the reliability and headroom they need.

Supplied with a billet aluminium fuel rail, this kit is the ideal foundation for hybrid turbo, ethanol and high-boost setups.

Key Features

• Enlarged aluminium plenum for increased airflow and charge volume

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

• Reduced pressure drop vs OEM manifold for more efficient boost utilisation

• Billet aluminium fuel rail included (MPI-ready)

• Integrated MPI ports (injectors/harness not included)

• Reinforced TIG-welded construction for high-boost durability

• Direct-fit design with OEM sensor compatibility

• Ideal for ethanol blends (E30–E85) and upgraded fuelling strategies

• Supports hybrid and big-turbo S58 applications

Compatibility

BMW S58 Models

• G80 M3 / G81 M3 Touring

• G82 M4 / G83 M4 Convertible

• F97 X3 M / X3 M Competition

• F98 X4 M / X4 M Competition

(Fits all BMW models equipped with the S58 engine.)

Ideal For

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

• Cars running ethanol blends requiring increased fuelling capacity

• Track, drag and high-load applications where the OEM manifold becomes restrictive

• Drivers who need stable airflow distribution at higher boost pressures

• Builds planning to integrate multi-port injection alongside factory DI

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

The OEM S58 manifold is made from plastic and quickly becomes a bottleneck in high-boost scenarios, restricting flow and limiting fuelling options.
Wagner’s EVO1 manifold solves this with a robust, motorsport-grade aluminium design featuring a large plenum and smooth internal geometry that improves airflow efficiency and cylinder-to-cylinder stability.

The included billet fuel rail adds essential fuelling headroom and prepares the system for MPI integration — providing safer combustion, improved knock resistance and the ability to support significantly higher power levels.

With premium construction, precise fitment and proven performance, this kit is one of the strongest intake upgrades available for the S58 platform.

Installing / Notes

• MPI injectors, lines and controller not included

• ECU calibration required to enable MPI

• Professional installation recommended

• Works with OEM and aftermarket intercoolers/charge pipes

• Coolant/fuel system may require bleeding after installation
