BMW Radiators

BMWs turbocharged S55 engine uses a water-to-air charge air cooling system, with a front-mounted heat exchanger responsible for heat dissipation. Unfortunately, the factory single-row, 27mm core design is quick to heat soak under high load, leading to excessive intake air temperatures and potential limp mode conditions especially on modified or track-driven cars.

To solve this issue, we've developed a drop-in upgrade over the factory unit. Engineered for durability and maximum cooling efficiency, this heat exchanger is a must-have for high-horsepower street builds, spirited canyon driving, and extended track sessions. Built from TIG-welded 5052 aluminum, our design eliminates the factory plastic end tanks one of the systems most common failure points. Each heat exchanger features CNC-machined billet aluminum hose connections, mounting flanges, and brackets for perfect OE fitment and trouble-free installation.

By replacing the OEM 27mm single-row core with a robust 35mm dual-row design, this heat exchanger dramatically increases both cooling capacity and surface area. Frontal area jumps from 307mm to 475mm, resulting in a 100% increase in coolant volume and significantly improved heat-soak resistance. The outcome? Lower, more stable charge air temperatures that help your S55 deliver consistent, reliable power on the street or at the track.

Features:

5052 aluminum construction eliminates plastic end tank failures A performance-oriented, dual-row core provides a 55% increase in frontal surface area, and a 100.29% increase in coolant volume over the OE heat exchanger! OE Heat Exchanger: Single-row core 27mm core thickness 307mm core height ECS High Performance Aluminum Heat Exchanger: Dual-row core 35mm core thickness 475mm core height TIG-welded 5052 aluminum end tanks, polished to a mirror finish for a high-quality look CNC-machined connectors and bracketry ensure seamless fitment with factory cooling hoses, transmission cooler lines, condenser, and radiator Drop-in upgrade - no modifications required for installation! Product Development:

Our High Performance Aluminum Heat Exchanger was designed, engineered, tested, and quality inspected by our Research and Development team in our Wadsworth, Ohio, facility. We strive for the highest level of precision and quality through leading-edge product development technology, including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.

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

Upgrade your cooling system setup with our Heavy Duty Radiator Mounting Brackets, engineered to deliver maximum structural support and a refined engine-bay aesthetic. After decades of heat cycles and hard driving, your E30's factory plastic mounts inevitably become brittle, faded, and prone to cracking, risking damage to your radiator. Our radiator mount upgrade completely replaces those tired OEM units with a high-strength alternative built to handle the rigors of spirited driving, track days, and engine swaps. Whether you are performing a full cooling system refresh or executing an M5X swap that utilizes an E36-style radiator, these brackets provide the ideal balance of precision fitment and rugged dependability.

Crafted with a premium brushed stainless steel finish, this kit does more than secure your radiator; it radically improves the visual appeal under the hood by swapping out cheap, weathered plastic for durable steel hardware. Designed as a true direct bolt-on solution, the brackets align seamlessly with factory mounting locations, eliminating the need for frustrating custom fabrication, cutting, or drilling. They clamp down firmly to eliminate unwanted radiator movement, ensuring your cooling stack remains locked in place under heavy vibration.

Whether you're refreshing your cooling system or replacing aging components, this ECS Silicone Upper Radiator Hose is the ultimate upgrade. Designed for durability, performance, and a factory-perfect fit, these premium silicone hoses outperform standard rubber in every way.

Made from heavy-duty, reinforced 4-ply fluorosilicone, this ECS hose can withstand extreme temperatures and pressures far beyond OEM rubber.
