The 3.0 Liter S55B30 turbo engine for BMW M2/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 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 front mounted radiator: 590 mm x 308 mm x 25 mm / 23,2Inch x 12,1Inch x 1,0Inch V = 4,5 Liter A = 1817 cm² / 280,7Inch² Dimensions WT front mounted radiator: 568 mm x 468,4 mm x 32 mm / 22,4Inch x 18,4Inch x 1,26Inch V = 8,5 Liter (+89%) A = 2660,5 cm² / 412,2Inch² (+46,4%) Kit comes with: 1x front mounted radiator (low-temperature circuit) 1x installation instruction

BMW F8X M3 M4 CTS Performance Heat Exchanger is designed to provide superior cooling for the BMW S55 engine platform, addressing the inefficiencies of the factory-installed heat exchanger. The factory front-mounted heat exchanger often struggles to keep tuned S55 engines cool, but this high-performance solution from Turner Motorsport is engineered to enhance cooling efficiency. Featuring a double-pass core, this heat exchanger is both larger and more effective than the factory unit while fitting perfectly into the stock location. Precision CNC-machined mounting points and hose connections ensure a seamless installation without the need for any cutting or trimming. Additionally, the integrated vent simplifies air bleeding from the cooling system after installation.

Enhanced cooling: Provides superior cooling for tuned S55 engines, overcoming the limitations of the factory heat exchanger.
Double-pass core design: Larger and more efficient than the stock unit for improved heat dissipation.
Seamless installation: CNC machined mounting points and hose connections ensure easy installation without modifications.
Integrated vent: Facilitates easy air bleeding from the cooling system post-installation.
Vehicle compatibility: Specifically designed for BMW F8X M3 and M4 models with the S55 engine.

Upgrade to the BMW F8X M3 M4 CTS Performance Heat Exchanger from Turner Motorsport for optimal cooling and enhanced performance.

BMW's S55 motor is a modern marvel but one weak point, which Active identified is the entire cooling system for the intake which comprises the charge pipe, the aftercooler and the heat exchanger (or radiator). Finally there is a S55 aftercooler kit upgrade that is good enough to carry the Active Autowerke brand. Years of success in developing cars for motorsport has allowed Active to leverage its expertise to the top-mount charge air cooler on the F80 M3, F82 M4 and F87 M2 Competition. This aftercooler was made for the S55 and crafted using only high-grade aluminum to outperform the factory aftercooler in all situations from everyday driving to the toughest racing. The factory cooler was built to support a specific power target and environment. Many of you have increased the performance of the S55 which quickly overwhelms the stock cooler leading to heat soak and higher intake air temperatures which triggers the ECU to downgrade the performance until cooler air returns. Active's focus was not on a mass-market aesthetic add-on but a properly engineered improvement over the existing hardware. Active uses a tube-and-fin core designed specifically for the S55 and included turbulators to maximize the cooling efficiency in as small a package as possible. The end tanks are billet machined aluminum, not cast, folded, or bonded and ensure even distribution of the water throughout the internal aftercooler cores. High precision fittings, CNC machining, and TIG welding throughout ensures the highest quality construction to prevent pressure loss, and the lowest weight, in a bolt-on replacement. But Active also didn’t leave the aesthetics by the wayside as we dip the visible top of the aftercooler in a carbon fiber coating giving your installed cooling system a decidedly top market look to match the improved cooling performance. The Active silicone charge pipes for the F80 M3, F82/F83 M4 and the F87 M2 Competition improve the flow over the stock, compressed plastic pipes. The Active Silicone Charge Pipes allow you to maximize power on your F8X by securing all the boost that your S55 is making. These pipes replace the hot-side pipes leaving the turbos and into the top-mount aftercooler. The stock S55 charge pipes are notorious for developing hairline fractures at their plastic seams. These fractures or cracks are unnoticeable to the naked eye, but under boost pressure they open up leaking the desired charged air into the engine bay, and consequently can rob your S55 of it's full power potential. In addition, these leaks can trigger your S55's turbochargers to work harder to hit and maintain target boost pressure, potentially wearing them out sooner. Active uses silicone in this area because it will not contribute to heat soak and it's easier to mold for the correct clearances. Active uses a 5-layer silicone hose with all needed adapters and stainless hose clamps included. It fits perfectly with our CNC’d top-mount cooler.
