The water pump is a known weak point across all BMW models, requiring servicing every 60,000 miles. Along with the water pump, it’s wise to replace the thermostat to ensure your cooling system operates at peak efficiency.

This kit features a 90°C (194°F) thermostat from Hamburg Technic, which opens approximately 15°C earlier than the standard factory thermostat. This lower temperature is particularly advantageous for performance-focused applications.

What's Included:

Genuine BMW Mechanical Water Pump Assembly (11517846361) Hamburg Technic Performance Thermostat - 90°C/194°F (11537586885) Genuine BMW Coolant/Antifreeze - Diluted, 1 Gallon (82141467704) Benefits of a Lower Thermostat Temperature:

Enhanced Engine Cooling: Opens sooner to reduce engine temperature more effectively. Improved Performance: Keeps engine components cooler, allowing for better performance in high-stress conditions. Extended Engine Life: Reduces thermal stress on engine parts, promoting longevity. Prevents Overheating: Helps to avoid overheating in demanding driving scenarios. Optimized Fuel Efficiency: Maintains ideal engine temperature for efficient fuel combustion. Elevate your BMW's cooling system and performance with this expertly curated kit from Turner Motorsport.

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.
