The 3.0 Liter S55B30 turbo engine for the BMW M3/M4 models is 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 water cooler comes into play. The new developed competition racing cores of the WAGNERTUNING high performance water coolers increase the radiator volume of the OEM water coolers by 89% for front mounted and 94% for side mounted. 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 side mounted radiator: 250 mm x 165 mm x 40 mm / 9,8Inch x 6,5Inch x 1,6Inch V = 1,65 Liter A = 412,5 cm² / 63,7Inch² Dimensions WT side mounted radiator: 252 mm x 188 mm x 68 mm / 9,9Inch x 7,4Inch x 2,7Inch V = 3,2 Liter (+94%) A = 473,8 cm² / 73,3Inch² (+14,9%) Kit comes with: 1x side mounted radiator (low-temperature circuit) 1x carbon air shroud for side mounted radiator 1x mounting material 1x installation instruction

If your vehicle is experiencing cooling issues, chances are the thermostat is the cause. Common symptoms include prolonged warm-up at highway speeds from the thermostat being stuck open, or consistent overheating issues from the thermostat being stuck in the closed position. Either condition can result in poor performance, and potential damage to vital components in your vehicle.
