10X Entries For Our Spin To Win Sweepstakes!
Ditch your failure-prone plastic end tanks and increase cooling capacity by 25%—all without modifying your core support or accompanying shrouds. The CSFxTurner Performance Triple-Pass Radiator is the best 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.
Recognizing the critical need for increased cooling capacity, the team at Turner Motorsport partnered with CSF Race, world leaders in high-performance cooling systems with over 50 years of experience. The result is the Performance Triple-Pass Radiator: a high-performance, motorsport-grade upgrade engineered to keep your E46 M3 cooler.
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 & 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
NOTE: A few users have reported higher operating temperatures after installing the Triple-Pass radiator. Turner's testing confirmed that coolant temperature does not exceed 204°F (96°C) at 80°F (26.5°C) ambient temperature if properly bled. If you're experiencing increased coolant temperatures post-installation, we recommend bleeding the cooling system with a vacuum bleeder (see ES#2712734).
