Wagner Tuning BMW B58.1 EVO1 Cast Chargecooler

Wagner Tuning BMW B58.1 EVO1 Cast Chargecooler

The Wagner Tuning EVO1 Cast Chargecooler is a complete intake manifold with an integrated intercooler, engineered specifically for the BMW 3.0 litre B58.1 turbo engine. By combining the manifold and chargecooler into one cast unit, it replaces the standard setup with a far more capable cooling solution that helps your engine make consistent power, even when pushed hard.

A chargecooler (sometimes called an intercooler) lowers the temperature of the compressed air leaving the turbo before it enters the engine. Cooler air is denser, which means more oxygen, better combustion and more reliable performance, especially during repeated hard driving or on track.

Why Upgrade the Standard Chargecooler?

The factory cooler on the B58.1 is a known weak point once power levels start to climb. Heat soak causes intake temperatures to rise quickly, which leads to the ECU pulling timing and reducing boost to protect the engine. The Wagner unit addresses this directly with a much larger core and improved internal airflow.

• Up to 20°C lower intake air temperatures for more consistent power
• 128% larger external core volume compared to the OEM cooler
• 35% less backpressure, reducing strain on the turbocharger
• 100% pressure tested for safety at higher boost levels
• Plug and play fitment with no modifications required
• Suitable for stock cars through to high-output builds

Design and Construction

The cast aluminium manifold houses a performance core developed specifically for the demands of the B58.1. The end tanks have been refined using CFD (computational fluid dynamics) simulations and CNC machined for smooth airflow, helping the cooler shed heat efficiently with minimal restriction. A heat-conducting anti-corrosion coating is applied to the core to maintain long-term cooling efficiency.

The optimised ratio between the internal and external cooling surfaces means heat transfer is maximised without choking airflow into the engine, making this kit equally at home on a daily-driven car or a dedicated track build.

Built-In Tuning and Measurement Provisions

The manifold has been pre-prepared with several useful features for tuners and enthusiasts:

• Provision for intake manifold fuel injection (Fuel Rail available separately)
• Three 1/8 NPT ports for additional sensors or parameter logging
• Six prepared ports for NOS or WMI (water/methanol injection), for example 90° NOS nozzles in 1/16 NPT

Servicing Made Easy

Important: the oil filter can still be replaced without removing the intake manifold, so routine servicing is unaffected by the upgrade.
