    Wagner Tuning Competition Front Water Cooler for BMW G8x M2/M3/M4 (S58) – 60% more volume, including certification

    Now with parts certification! The Wagner Tuning Competition Front Water Cooler Kit is the ultimate upgrade for thermal stabilization of your BMW M2 (G87), M3 (G80/G81), and M4 (G82). Specially developed for the 3.0L R6 biturbo engine (S58), it increases the cooler volume by a massive 60%. Ensure consistent maximum performance and reliability – now including parts certification.

    Why this front water cooler is a must-have for your BMW M (S58):

    Massive increase in volume: The competition racing intercooler core increases the cooling capacity of the standard water cooler by an impressive +60% (14.67 liters vs. OEM 9.16 liters).
    Approved & legal: Supplied with parts certificate for maximum safety and uncomplicated registration.
    Direct performance increase: Effectively lowers the coolant temperature in the indirect intercooler circuit. This improves intercooler cooling and stabilizes the system thermodynamics.
    Maximum heat transfer: The optimal ratio between internal and external cooling surface, achieved by increasing the construction depth, guarantees maximum heat transfer.
    Durably reliable: Equipped with a heat-conducting anti-corrosion coating for long-term cooling effect and system protection.
    Plug & play installation: Installation is straightforward and plug & play thanks to detailed installation instructions.

    Technical detail: Cooling circuit optimization for the BMW S58 engine
    The 3.0L R6 biturbo engine (S58) in BMW M models (G87, G80, G81, G82) uses an indirect intercooler circuit (low-temperature circuit). The charge air is cooled via a separate cooling water circuit. Lowering the cooling water temperature is therefore the critical factor in maintaining engine performance, especially during aggressive driving or performance enhancements.
    The Wagner Tuning upgrade water cooler solves this bottleneck with a 60% increase in volume, which is primarily achieved by increasing the installation depth (from 30 mm to 48 mm). The increased coolant volume keeps the entire system temperature at a lower level over a longer period of time – essential for the 480 hp to 550 hp models.

    The Wagner Tuning Competition water cooler kit is plug-and-play compatible with the following models with the S58 engine:
    BMW G87 M2 (460 hp, from 2023+)
    BMW G80/G81 M3 (Base/Competition/Touring, 480–510 hp, from 2021+)
    BMW G82 M4 (Base/Competition/CSL, 480–550 hp, from 2021+)

    Technical data in direct comparison (OEM vs. Wagner Tuning)
    The Wagner Tuning front water cooler offers decisive advantages over the standard part:
    Volume (V): From OEM 9.16 L to 14.67 L (increase +60%).
    Dimensions (depth): From OEM 30 mm to 48 mm.
    Area (A): Remains the same (3055 cm²), with significantly greater depth.

    Dimensions OEM water cooler:
    505 mm x 605 mm x 30 mm
    V = 9.16 liters
    A = 3055 cm²

    Wagner Tuning water cooler dimensions:
    505 mm x 605 mm x 48 mm
    V = 14.67 liters
    A = 3055 cm²
