    Wagner Tuning Competition Water Cooler Kit for BMW G20/G21/G28/G22/G23/G26 – 80% more volume & plug-and-play

    Optimize the cooling performance of your BMW 3 Series or 4 Series! With our Wagner Tuning Competition Water Cooler Kit, you can improve your vehicle's indirect intercooler circuit. This upgrade is the ideal solution for lowering the coolant temperature and taking performance to a new level. Prepare your BMW for maximum performance and experience the benefits of optimized cooling.

    Why our water cooler is the best choice for your BMW:
    Massive cooling performance: Our newly developed Competition racing core increases the cooler volume of the standard water cooler by an impressive 80%. Lowering the coolant temperature directly improves the cooling performance of the charge air.
    Improved efficiency and durability: The water coolers are equipped with a heat-conducting anti-corrosion coating that ensures long-term and effective cooling.
    Simple plug-and-play installation: The system can be installed using our detailed installation instructions and simple adjustments in a plug-and-play process.

    Suitable for
    BMW 3 Series (G20/G21/28): 320i*, 325i*, 330i (xDrive), 330e (xDrive), M340i (xDrive)
