BMW Radiators for BMW F82 M4 S55 3.0L

Clear BMW chassis

Please ensure your correct model is selected

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.

Like the other cooling systems on the F8X, the factory auxiliary radiators do a pretty good job in stock form. However, once you start adding a lot of power and pushing the car in aggressive driving conditions, the factory systems start to show its limitations. As more and more owners have pushed the limits of their S55, CSF saw the need and demand. The F8X platform is also almost a decade old with the newest examples being at least 5 years old. Over time the original coolers end up with damaged or clogged fins that greatly reduce their cooling capacity. CSF designed the coolers to be a true “Drop-in Fit” for easy installation. Each cooler mounts in the factory location and uses the OEM quick connections. The High-Performance Auxiliary Radiators work in conjunction with the rest of the cooling system to reduce temperatures. They not only help keep temperatures in optimal ranges, but prolong the heat soak threshold. There’s nothing worse than having your track session cut short because you need to do a cooldown lap. Each CSF F8X Auxiliary Radiator can fit the left or right side. The fitting and plugs are swappable and can be easily setup for either side. Compared to the OEM F8X coolers, the CSF units are a significant upgrade. CSF eliminated the OE plastic mounting pod by incorporating it into the modular design that fits both sides. This design improvement increases the size of both the core and tanks. The extra space taken from the mounting pod allowed for a ~7% increase in Core Size and an ~10% increase in Tank Volume. With a larger 2-row 42mm core, cooling efficiency and capacity are drastically increased. The high efficiency core using CSF’s Exclusive B-Tube Technology maximizes airflow and heat dissipation. 100% All-Aluminum construction ensures the best performance and durability. The mounting pins and brackets are much stronger and more durable than the OE plastic pod mounting system. In addition, the black finish provides extra protection and offers a stealthy look behind the grilles of your F8X. In addition, the CSF auxiliary radiators also feature integrated bolt on rock guards to keep the coolers safe. You’ve no doubt heard horror stories about OEM coolers getting punctured and spilling fluids all over the road or track. Now you can feel more confident that your cooling system is safer from road debris. CSF used a modular design so the auxiliary radiator can fit either side. There are several benefits to this type of design and offers several benefits. One of those benefits is for serious track applications. Having spare parts is always a great idea. Having one auxiliary radiator that fits both sides where you’d normally need one of each is a big cost and space saver. Getting an extra as backup is more cost/space efficient with the CSF units.

If you are looking to track your BMW, we recommend upgrading your front mount heat exchanger with this upgrade from CSF! CSF heat exchangers offer larger cores with greater cooling capacity. They feature their exclusive "B-Tube" technology--lighter, thinner aluminum material carefully formed in a "B" and brazed over the seam to seal. The design is stronger and offers better cooling efficiency than traditional "O" shaped tubes.

Replace your inefficient factory front-mounted heat exchanger with the VRSF Competition upgrade kit to get the most performance and reliability out of your M2C, M3 & M4 with the S55 engine. They designed this kit to be one of the best performing, direct bolt on intercoolers available for your BMW with special attention to quality and performance while maintaining a reasonable price. Our intercoolers allow for higher HP gains, mainly due to their ability to keep intake temps down while preventing heat soak which is a common problem with the factory intercooler. This results in a more power and increased reliability with reduced chances of pre-detonation & knock.

BMW F8X M3 M4 CTS Performance Heat Exchanger is designed to provide superior cooling for the BMW S55 engine platform, addressing the inefficiencies of the factory-installed heat exchanger. The factory front-mounted heat exchanger often struggles to keep tuned S55 engines cool, but this high-performance solution from Turner Motorsport is engineered to enhance cooling efficiency. Featuring a double-pass core, this heat exchanger is both larger and more effective than the factory unit while fitting perfectly into the stock location. Precision CNC-machined mounting points and hose connections ensure a seamless installation without the need for any cutting or trimming. Additionally, the integrated vent simplifies air bleeding from the cooling system after installation.

  • Enhanced cooling: Provides superior cooling for tuned S55 engines, overcoming the limitations of the factory heat exchanger.
  • Double-pass core design: Larger and more efficient than the stock unit for improved heat dissipation.
  • Seamless installation: CNC machined mounting points and hose connections ensure easy installation without modifications.
  • Integrated vent: Facilitates easy air bleeding from the cooling system post-installation.
  • Vehicle compatibility: Specifically designed for BMW F8X M3 and M4 models with the S55 engine.

Upgrade to the BMW F8X M3 M4 CTS Performance Heat Exchanger from Turner Motorsport for optimal cooling and enhanced performance.
