BMW Radiators for BMW G87 M2 S58 3.0L

Clear BMW chassis

Please ensure your correct model is selected

We sell only OE supplier or approved aftermarket upgrade radiators for your BMW. It seems BMW took some shortcuts when it came to radiator design and used weak materials like plastic for critical connection points. If you are tracking older models like E30, E36, or E46, you probably are well aware of these issues. As these cars age, the plastic pieces become more brittle and failure prone. The solution is to replace with upgraded radiators that perform as upgrades for the original, failure prone radiator to avoid being left on the side of the road or, worse yet, the track.

CSF designed the coolers to be a true “Drop-in Fit” for easy installation fitting both left and right sides. Each cooler mounts in the factory location and uses the OEM quick connections. The High-Performance Auxiliary Radiators work in conjunction with the rest of the cooling system to reduce temperatures. They not only help keep temperatures in optimal ranges but also prolongs the heat soak threshold. There’s nothing worse than having your track session cut short because you need to do a cooldown lap.

Compared to the OEM G8X coolers, the CSF units are a significant upgrade. The TIG welded aluminum tanks are much larger than the OE plastic tanks offering superior strength and fluid volume. A larger 2-row 42mm core increases cooling efficiency and capacity. This high-efficiency core uses CSF’s Exclusive B-Tube Technology and the latest 5mm fin technology, maximizing airflow and heat dissipation. These 5mm fins significantly increase the heat exchange surface area improving overall cooling efficiency and recovery while still maintaining good airflow.

100% All-Aluminum construction ensures the best performance and durability. The mounting pins and brackets are much stronger and more durable than the OE plastic pod mounting system. In addition, the black finish provides extra protection and offers a stealthy look behind the grilles of your G8X.

The CSF auxiliary radiators also feature integrated bolt on rock guards to keep the coolers safe. You’ve no doubt heard horror stories about OEM coolers getting punctured and spilling fluids all over the road or track. Now you can feel more confident that your cooling system is safer from road debris.

Because each auxiliary radiator is used for a different system you can elect to replace one at a time. For those looking to further improve the Charge Air Cooling system replace the right side auxiliary radiator. Those looking to improve the engine cooling system should replace the left side.

This performance heat exchanger from CTS features a number of upgrades over the stock intercooler, offering better reliability and cooling performance. The first major upgrade is the heat exchanger's full alumnimum constructions. The factory heat exchange is partially constructed from plastic, which is prone to damage and cracks as the plastic becomes brittle over time. Full aluminum construction results in a stronger intercooler, which will last the lifetime of your BMW. The second major upgrade is a redesign of the coolant flow path and fin layout. This redesign allows for higher cooling efficiency, resulting in greater heat dissipation and reduced coolant temperatures.

The 3.0L I6 bi-turbo engine of BMW M3/M4 models is equipped with an indirect charge-air cooling circuit. So the cooling of the charged air is not realized by the ambient air as cooling medium (as usual), but made with its own cooling water circuit. A reduction of the temperature of the cooling water is directly equated with an improved cooling performance of the charged air. This is exactly where the advantages of the WAGNERTUNING upgrade water cooler comes into play. The new developed competition racing core of the WAGNERTUNING high-performance water coolers increases the radiator volume of the OEM water coolers by a total of 60 %. The calculated ratio between the inner and outer cooling surface generates a maximum heat transfer and allows at the same time enough air flow for the surrounding components (for example the engine water cooler) for its own heat exchange. The water coolers are equipped with a heat-conductive anti-corrosion coating to ensure a lasting cooling effect. The plug & play installation of the system is simple and easy to perform (an installation instruction is included as well). Dimensions OEM radiator: 505 mm x 605 mm x 30 mm V = 9.16 Liter A = 3055 cm² Wagner Dimensions 505 mm x 605 mm x 48 mm V = 14.67 Liter A = 3055 cm²
