Ditch your failure-prone plastic end tanks and increase cooling capacity by 25%—all without modifying your core support or accompanying shrouds. This Performance Triple-Pass Radiator is the ULTIMATE cooling system upgrade for your S54-equipped BMW!

The E46 M3 is a masterclass in German engineering. Harboring six independent throttle bodies, infinitely variable dual-VANOS, and an 8,000 RPM redline, the S54 is practically a racing engine for the road. Unfortunately, the engine's motorsport pedigree didn't quite make it to the cooling system. The OEM radiator, while superior to its non-M counterpart, struggles to keep coolant temperature in check under sustained high-RPM conditions. Heat soak, elevated operating temperatures, and component fatigue are all too familiar to M3 owners who track their S54 regularly.

To solve this problem, we teamed up with CSF Race, a global leader in high-performance cooling solutions with over five decades of industry experience. Together, we developed the CSFxTurner Triple-Pass Radiator: a high-performance, no-compromise solution built to meet the cooling demands of track-day warriors.

Part Design:

CSF-Exclusive "B-Tube" Technology Unlike conventional "O-tube" designs, CSF’s patented B-tube structure increases wall strength while creating a more efficient flow path. This alone accounts for a 15% increase in cooling capacity over an OE "o-tube" radiator! Triple-Pass Core Design As the name suggests, this unique structure forces coolant through the core three times before exit, resulting in a substantial temperature delta across the radiator core. Two-Row Compact Structure This radiator was designed with precise fitment in mind. While total tube count and size are increased, the overall radiator dimensions stay the same as OE, ensuring a drop-in fit with zero modifications required. 25% Increase in Cooling Capacity All of the above design features translate to a massive 25% cooling increase over the stock radiator! Features & Performance Benefits:

Direct-fit upgrade—no modifications required! Accepts all OEM attachments via CNC-machined "Quick-Connect" hose ends and accessory mounting provisions TIG-welded aluminum construction provides increased durability An all-aluminum drain plug replaces the weak OE plastic unit, ensuring seamless functionality for the life of the radiator Increased cooling efficiency for high-performance and racing use Designed and tested by Turner Motorsport in collaboration with CSF Race

CSF is one of the premier cooling product specialists available on the market thanks to designs such as their High Performance Aluminum Radiators. Using a single pass designed core, this radiator gives you all the cooling you could ever need. Paired with these radiators are CNC machined brackets and corrosion resistant hardware that allow final installation to have a same as stock fitment! This enables you to have much higher cooling without having to cut away any metal or delete any important components just for the sake of lower coolant temperatures. 

Features:

• Two-row, triple-pass design radiator core
• CNC machined mounting brackets
• All needed hardware included
• Hand polished aluminum with a mirror-like finish
• Stock fitment prevents modification to engine bay

Looking to free up horsepower and upgrade your cooling? Then this Electric Fan Conversion kit is the perfect choice! The fan and clutch that connect to the water pump add additional rotating mass to the drive line. By removing them and converting your system to an electric fan, the engine has to do less work, giving you that extra little bit of power. In this kit we include a lower temperature thermostat, coolant additive, and low temperature fan switch that engages the electric fan at a lower temperature, keeping your engine cool and lowering the drag and unneeded weight from the front end of your BMW.

Included in this kit:

• 80 degree Celsius thermostat
• 1 liter of Genuine BMW coolant
• Water Wetter coolant additive
• Low-temperature coolant temperature sensor/switch
• 16 inch Electric fan 
• Electric fan mounting kit
• Fan controller kit with probe sensor 
• Fan delete nut

Fits the following BMWs:

Just like the rest of your vehicle's major systems, the cooling system must also be addressed periodically to ensure proper cooling and component reliability. Plastic and rubber components become brittle and prone to splitting or cracking after long periods of heating and cooling cycles, especially in colder climates! The coolant itself can degrade or become contaminated, leading to potential corrosion or freezing issues. Finally, thermostats and sensors can fail completely, preventing proper cooling and/or coolant temperature readings to become inaccurate.

To make sure you are not left stranded on the side of the road with an overheated engine, we have put together this Basic Cooling System Service kit. This kit contains all of the most-likely-to-fail components, giving you peace of mind knowing your engine will continue to run cool for another 60,000+ miles.

See kit contents below for all included components.

The fan that attaches to the water pump carries so much rotational mass that it can actually hinder the performance of your engine.
