BMW Radiators for BMW A90 MKV Supra B58 3.0L

Clear BMW chassis

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.

The factory front-mounted heat exchanger is small and not efficient enough to provide enough cooling to tuned B48/B58 engines. CTS designed this heat exchange to overcome that problem. The double-pass core was made to be higher flowing and larger than the factory but still drop into the stock location. CNC machined mounting points and hose connections allow for a seamless install without any need to cut or trim any factory parts. Keep your B48/B58 running cool and reliably with the CTS Turbo Front Mount Heat Exchanger. Features: CNC machined mounting points and hose connection for factory fitment Drop-in design Smooth bends on the coolant connections High-efficiency double-pass aluminum core Hand-welded and pressure tested Lowers intake air temperature Installation hardware included Fully compatible with factory rock guard, simply transfer the factory parts over

The 2.0 Liter B48 and the 3.0 Liter B58 engines for the G29 Z4 and MkV Supra are equipped with an indirect charge-air cooling circuit. This means 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 radiator come into play. The new developed competition racing core of the WAGNERTUNING high performance radiator increase the radiator volume of the OEM water cooler by a total of 117%. 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 radiator) for its own heat exchange. Furthermore, using an increased amount of cooling water, the entire system can be kept at a lower level over a longer period of time. All WAGNERTUNING radiators 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: 576 mm x 495 mm x 27 mm V = 7,70 Liter A = 2851 cm² Dimensions WT radiator: 524 mm x 468 mm x 68 mm V = 16,70 Liter A = 2454 cm²
