BMW Radiators

We sell only OE supplier or approved aftermarket upgrade radiators for your BMW. It seems BMW took some shortcuts when it came to radiator design and used weak materials like plastic for critical connection points. If you are tracking older models like E30, E36, or E46, you probably are well aware of these issues. As these cars age, the plastic pieces become more brittle and failure prone. The solution is to replace with upgraded radiators that perform as upgrades for the original, failure prone radiator to avoid being left on the side of the road or, worse yet, the track.

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.

Replaces OEM part numbers 17112284608 and 17112459062.

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

Track-tested and street-ready. the ULTIMATE cooling system upgrade for your N54 or N55!

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 N54/N55-equipped BMW!

The BMW 135i and 335i deliver serious performance straight from the factory, thanks to the twin-turbocharged N54 and single-turbo N55 engines. With strong midrange torque, high-revving capabilities, and proven tuning potential, these engines punch well above their weight. However, while the powertrain excels, the factory cooling system often falls short, especially under sustained boost or track conditions. Heat soak, rising coolant temps, and long-term thermal stress are common issues for enthusiasts pushing their N54 or N55 hard, making a performance radiator an essential upgrade for reliability and consistency.

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 an Upgraded Performance Radiator: a high-performance, motorsport-grade upgrade engineered to keep your N54/N55 cooler and on the track for longer.

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.

Every hero has its Achilles heel, and for many BMWs, it's the cooling system. Featuring an overabundance of brittle, crack-prone, leak-inducing plastic, the otherwise robust drivetrain is let down by a weak cooling system. Now, ECS has come to the rescue with a solution to cure those problems once and for all and leave the days of cracked plastic end tanks and coolant-stained driveways far behind. This radiator was designed with performance, durability, and good looks in mind to create a great all-around upgrade for any E36 owner, from the daily driver to the weekend warrior. Featuring fully aluminum construction, all the joints are precision TIG-welded for superior durability and show-car looks, with polished end tanks further adding to the great look of this radiator. The easily-stripped plastic drain plug and fan switch holes have been replaced with threaded alloy bungs in the stock locations, and the weak plastic tabs for the factory fan shroud have been replaced with beefy aluminum as well. Designed as a drop-in solution, this radiator will fit like a stock replacement, but will look and perform far better, while costing substantially less than the competition. What are you waiting for? Upgrade your cooling system today and leave your worries behind - and look great doing it - with this ECS Tuning Performance Aluminum Radiator. Note: Owners of automatic E36s utilizing a stock-style transmission cooler must drill two small holes in the lower frame of the radiator.

Maximize cooling efficiency and take your BMW’s performance to the next level with the ECS High Performance Cooling System Bundle—a complete, track-proven upgrade engineered to handle the extreme thermal demands of the G2X B58 platform. Developed by the enthusiasts at ECS Tuning, this system includes both the High Performance Aluminum Radiator and High Performance Aluminum Heat Exchanger, designed to deliver consistent, reliable temperature control in even the most demanding driving conditions.

The factory BMW cooling components just aren’t built for high-performance or track use. Both the OE radiator and heat exchanger feature weak plastic end tanks and undersized single-row cores—common failure points when exposed to elevated heat and pressure. ECS set out to solve these shortcomings with an all-aluminum, dual-row system designed for enthusiasts who demand more from their BMW. ECS engineers started by replacing the fragile plastic end tanks with TIG-welded 6061-T6 aluminum for unmatched durability. Each tank is precision-crafted with CNC-machined billet aluminum hose connections, flanges, and brackets, ensuring direct OE-style fitment with the factory hoses, fan shroud, and accessories—no cutting or modifications required.

Both the radiator and heat exchanger feature high-capacity, dual-row 42mm cores, a massive improvement over the factory’s 34mm and 25mm single-row designs. The result? Faster heat dissipation, lower intake air temperatures, and more consistent performance, whether you’re cruising or carving apexes.

When it comes to serious performance driving, the stock BMW G2X radiator quickly shows its limits. Like many factory BMW cooling systems, it relies on molded plastic end tanks that are notorious for cracking and leaking over time. Additionally, its single-row, 34mm-thick core offers poor cooling capacity for high-horsepower or track-driven cars.

To address these shortcomings, ECS developed the ultimate cooling solution for the G2X B58 platform�a High-Performance Aluminum Radiator designed, engineered, and tested by their in-house BMW specialists. Built to handle the increased thermal demands of high-horsepower builds and extended track sessions, this radiator delivers both unmatched durability and significantly improved heat dissipation.

Each unit features fully TIG-welded 6061-T6 aluminum end tanks, eliminating the weak points found in the OE design. Precision CNC-machined hose connections, flanges, and mounting brackets ensure a perfect drop-in fit with factory hoses, the fan shroud, and auxiliary components. No modifications required � just direct performance.

At the heart of the design lies a dual-row, 42mm-thick core, increasing total coolant volume and surface area for improved heat transfer. Compared to the factory�s 34mm single-row core, this upgrade translates to cooler operating temperatures and consistent performance under demanding conditions.

Features:

Full 6061-T6 aluminum construction eliminates plastic end tank failures Dual-row, 42mm performance core (45% thicker than OE) for increased cooling efficiency OE Radiator: Single-row, 34mm core ECS High Performance Aluminum Radiator: Dual-row, 42mm core TIG-welded aluminum end tanks for maximum strength and longevity Polished finish for a premium appearance CNC-machined fittings and brackets ensure seamless compatibility with factory hoses, transmission cooler lines, and condenser Direct-fit installation � no cutting or modifications required Replaces OEM Part Numbers: 17118666740, 17115A30677

Behr Replacement Radiator - More than likely, you are going to replace the radiator in your vehicle at least once. The joints where the cores meet the end tanks tend to get weak and are the first place to spring a leak. Impacts to the fins themselves can cause holes to form. Corrosion and clogging from the inside can make cooling less than effective and compromise coolant flow.

The radiator tank cap keeps necessary pressure on your coolant to increase efficiency. If you have an overheating issue in your vehicle, a simple, quick, and inexpensive part to replace is this cap. Often times, the coolant is not kept under enough pressure to keep it from boiling or expanding too much. This cap keeps all the heat and liquid inside the coolant system for maximum efficiency. Should be replaced each time major coolant system service is performed.
