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.

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 3.0 Liter S55B30 turbo engine for BMW M2/M3/M4 models is equipped with an indirect charge-air cooling circuit. So the cooling of the charged air is not realized by the ambient air as cooling medium (as usual), but made with its own cooling water circuit. A reduction of the temperature of the cooling water is directly equated with an improved cooling performance of the charged air. This is exactly where the advantages of the WAGNERTUNING upgrade water cooler comes into play. The new developed competition racing cores of the WAGNERTUNING high performance water coolers increase the radiator volume of the OEM water coolers by 89% for front mounted and 94% for side mounted. The calculated ratio between the inner and outer cooling surface generates a maximum heat transfer and allows at the same time enough air flow for the surrounding components (for example the engine water cooler) for its own heat exchange. The water coolers are equipped with a heat-conductive anti corrosion coating to ensure a lasting cooling effect. The plug & play installation of the system is simple and easy to perform (an installation instruction is included as well). Dimensions OEM front mounted radiator: 590 mm x 308 mm x 25 mm / 23,2Inch x 12,1Inch x 1,0Inch V = 4,5 Liter A = 1817 cm² / 280,7Inch² Dimensions WT front mounted radiator: 568 mm x 468,4 mm x 32 mm / 22,4Inch x 18,4Inch x 1,26Inch V = 8,5 Liter (+89%) A = 2660,5 cm² / 412,2Inch² (+46,4%) Kit comes with: 1x front mounted radiator (low-temperature circuit) 1x installation instruction

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.

Mishimoto X-Line E36 Aluminum Radiator features - 90% more capacity with thicker core 30 degree reduction in coolant temp All aluminum construction Hanger tabs for Euro oil cooler included More durable and longer lasting than plastic components Excellent fit and finish Unbeatable lifetime warranty and accident-forgiveness Mishimoto radiators address all of the defects of the stock E36 radiator in a well-engineered and price-competitive direct replacement unit. The Mishimoto X-Line radiator is an all aluminum design that replaces the factory plastic and aluminum stock radiator. The stock plastic end tanks are notorious for cracking and leaks whereas the Mishimoto has aluminum end tanks that will never fail. The X-Line uses a thicker core than stock for 91% more coolant capacity but still fits in the original location with no modifications. More coolant volume means the fluid is not heat soaked for as long (less super heated fluid circulating through the engine). For a direct replacement performance radiator, the Mishimoto is hard to beat! Mishimoto was established in 2003 as a supplier of cooling components for drift and rally cars. Their radiators and intercoolers soon found a strong following in the hyper competitive drift scene where high horsepower and prolonged high revs dictate the need for durable and robust cooling solutions. The catchy Mishimoto name is a combination of the name of the founder's family pet - Mishi - and "moto". All products are designed and tested in the USA using state-of-the-art CAD tools and prototyping and with continuous evolution of product design. Mishimoto is so dedicated to quality that they offer a limited lifetime warranty and accident forgiveness. WARNING! Prop 65 may apply to this product.

The F97 X3M and F98 X4M are powered by the same high-performance S58 engine found in the G8X M3, M4, and M2. While these SUVs deliver impressive power and speed, they also suffer from the same heat management challenges as their sedan and coupe counterparts. That’s where CSF’s advanced cooling solutions come in—becoming essential upgrades for S58 owners, even for those keeping their engines mostly stock. After over a year of development and testing, CSF is proud to introduce the Front Mount Heat Exchanger & Transmission Cooler Module for the F9X X3M and X4M. One of the biggest challenges in developing a Front Mount Heat Exchanger for these models was limited space. Unlike the G8X models, the X3M and X4M feature a different transmission oil cooler, restricting the available room for a larger heat exchanger due to the mounting cradle. After extensive testing with smaller core designs, CSF determined that integrating the Heat Exchanger with a Transmission Cooler Upgrade was the optimal solution for maximizing both size and performance. By combining both components into a single cooling module, CSF achieved a design that accommodates the same core size as the G8X Heat Exchanger. The integrated Auto Transmission Cooler utilizes the same dual-core design as the G8X Transmission Cooler and is seamlessly fitted to the new Heat Exchanger. This innovative all-in-one module not only addresses two major cooling issues for the X3M and X4M but also reduces overall costs—savings that are passed along to the customer. Compared to the stock heat exchanger, CSF’s upgraded design offers significant improvements. The TIG-welded aluminum tanks are much larger than the OE plastic tanks, providing superior strength and fluid volume. A 2-row 42mm core increases cooling efficiency and capacity, utilizing CSF’s Exclusive B-Tube Technology to enhance airflow and heat dissipation. Multi-louvered fins further expand the heat exchange surface area, improving overall cooling performance while maintaining proper airflow. Built entirely from high-strength aluminum, this system ensures maximum durability and reliability. The mounting tabs and brackets are significantly stronger than the factory plastic components, offering improved longevity. Additionally, the heat exchanger includes an integrated bolt-on metal rock guard, which is far more robust than the stock plastic version—providing better protection against road debris and ensuring greater confidence in the system’s resilience. CSF’s Transmission Cooler features an innovative dual-pass design that dramatically enhances cooling performance. Unlike the OEM single-core cooler, CSF’s front-to-back stacked core design more than doubles the surface area and nearly triples the core volume. Engineers leveraged the extra space freed up by replacing the OE cooler and oversized plastic cradle, effectively doubling cooling capacity while maintaining a perfect OEM fit—no modifications required. By switching from a single-core to a dual-core design, CSF achieved a 201% increase in overall volume, significantly improving heat dissipation and fluid capacity. Using CSF’s AC Condenser Technology, the cooler incorporates a high-pressure 1-row 16mm 9-channel microtube design, optimizing oil flow and maximizing surface area contact. These features work together to provide the most effective heat dissipation possible, keeping transmission temperatures under control even under extreme conditions. With CSF’s new Front Mount Heat Exchanger & Transmission Cooler Module, X3M and X4M owners can enjoy superior cooling efficiency, enhanced durability, and long-term performance—all in a cost-effective, OEM-fit package.

The 3.0 Liter S55B30 turbo engine for the M2 Competition is equipped with an indirect charge-air cooling circuit. This means the cooling of the charged air is not realized by the ambient air as cooling medium (as usual), but made with its own cooling water circuit. A reduction of the temperature of the cooling water is directly equated with an improved cooling performance of the charged air. This is exactly where the advantages of the WAGNERTUNING upgrade water cooler comes into play. The new developed competition racing cores of the WAGNERTUNING high performance water coolers increase the radiator volume of the OEM water coolers by 89% for front mounted and 94% for side mounted. The calculated ratio between the inner and outer cooling surface generates a maximum heat transfer and allows at the same time enough air flow for the surrounding components (for example the engine water cooler) for its own heat exchange. The water coolers are equipped with a heat-conductive anti corrosion coating to ensure a lasting cooling effect. The plug & play installation of the system is simple and easy to perform (an installation instruction is included as well). Dimensions OEM side mounted radiator: 250 mm x 165 mm x 40 mm / 9,8Inch x 6,5Inch x 1,6Inch V = 1,65 Liter A = 412,5 cm² / 63,7Inch² Dimensions WT side mounted radiator: 252 mm x 188 mm x 68 mm / 9,9Inch x 7,4Inch x 2,7Inch V = 3,2 Liter (+94%) A = 473,8 cm² / 73,3Inch² (+14,9%) Kit comes with: 1x side mounted radiator (low-temperature circuit) 1x carbon air shroud for side mounted radiator 1x mounting material 1x installation instruction

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. Replace your leaking unit with a factory replacement and get that jug of coolant out of your back seat.

Mishimoto radiators address all of the defects of the stock E46 radiator in a well-engineered and price-competitive direct replacement unit. The Mishimoto radiator is an all aluminum design that replaces the factory plastic and aluminum stock radiator. The stock plastic end tanks are notorious for cracking and leaks whereas the Mishimoto has aluminum end tanks that will never fail. Mishimoto can also build 30% more coolant capacity into the a radiator that fits in the original location with no modifications. More coolant volume means the fluid is not heat soaked for as long (less super heated fluid circulating through the engine). For a direct replacement performance radiator, the Mishimoto is hard to beat!
