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.

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. This is a factory original style radiator from CSF and will fit perfectly into the stock location. Cooling will be identical to what your car came with originally. A great replacement with all the proper connections and in all of the proper locations. When doing radiator and cooling service, you will obviously lose coolant. Browse through the cooling section of your model to see factory correct coolants, seals, and caps. Before beginning, check your hoses to make sure everything is in good shape.

The factory B4x/B58 heat exchanger is not built to cater to the rigorous demands often associated with a modified build. The thin core is easily overwhelmed with IAT's rising dramatically once pushed beyond a few successive WOT pulls or even a few minutes at the track. This elevation in temperature gives way to the factory ECU fail safes pulling timing and reducing overall power in order to keep the system from overheating to the point of permanent damage. On an application where enjoyment is directly attributed to pushing the platform to its limits this constraint to cooling presents a challenge for the automotive enthusiast. The Dinan B4x/B58 heat exchanger for the F2x/F3x chassis assists in mitigating these issues with a more robust core (48mm thick Dinan core vs. 27mm thick OEM core) that wields 78% more heat transfer surface area for improved cooling capacity. The significant increase in core thickness requires unique "L" shaped end tanks to be incorporated as well, which also contributes to the overall thermal mass (ability to absorb, store, and release heat) improvement beyond the OEM setup. With up to a 15° IAT delta recorded over stock the Dinan heat exchanger is ready, and able, to assist in extending your vehicles ability to deliver maximum performance time and time again for your driving enjoyment! Features: Average of 8° reduction in IAT's with a maximum reduction of 15° over 15 successive WOT pulls Reduces the tendency to heat soak / go in to limp mode 48mm thick Dinan cooler vs. 27mm thick stock cooler 78% more cooling surface area and volume than stock 100% TIG welded and pressure tested Installation hardware included (inclusive of xDrive specific transmission oil cooler brackets) NOTE: Due to the enlarged core and unique "L" shaped endtanks minor modification to the plastic core stack shroud may be required with some factory configurations ( particularly those with the optional OEM hot climate heat exchanger). Consult the installation PDF for full documentation on what exactly that entails. (https://documents.dinancars.com/d780-0002.pdf)

As most 335 owners have discovered, the cooling system is vital to maintaining high levels of boost. The car's sophisticated electronics wisely shut down and limit boost when temperatures are elevated enough to do potential harm. Don't short-change your cooling system or performance on the street or the track! Where the stock radiator suffers is in capacity, which is why BMW also sells an additional radiator and other cooling upgrades with their Performance packages. This radiator for the E90/E92 335 and E82 135/1M is a larger 40mm core (2mm thicker than stock) for additional capacity and bulletproof cooling. It fits in the stock location, with the stock shroud and fan (some plastic trimming may be necessary), maximizing the available space to dedicate to fluid capacity and surface area. Having a greater capacity means less saturation time for the cooling fluid which leads to more consistent engine temperatures, reducing the possibility of limp mode condition and reducing wear and tear on other cooling components such as the water pump and thermostat. If you're looking for the most complete and unbeatable radiator solution for your E9X, this is the best we have seen. Not only is this radiator larger, but it's also designed with the stresses of motorsports in mind. The cooling vanes use a unique oven-brazed bonding technology that will not fatigue and crack like epoxyed construction. Aircraft-grade aluminum is used for the tanks and frame, which are TIG-welded for superior strength. This radiator is a direct replacement for the stock E9X radiator, with all of the same hose locations and fittings as the original radiator. Because of the extra depth required between the radiator and engine, extra care will be needed when installed with upgraded intercoolers, intake piping, and oil coolers. This aluminum radiator is a replacement for the stock BMW radiator 17 11 7 558 480 and fits the 135i and 335i/xi (automatic transmission only). This item fits the following BMWs: 2008-2012 E82 BMW 135i 1M Coupe - with auto transmission only 2006-2011 E90 BMW 335i 335xi 335i xDrive - Sedan - with auto transmission only 2007-2013 E92 BMW 335i 335is 335xi 335i xDrive - Coupe - with auto transmission only 2007-2013 E93 BMW 335i - Convertible - with auto transmission only 2009+ Z4 BMW Z4 28i Z4 35i WARNING!

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.

Radiator: Replaces OEM part numbers 17118666740 and 17115A30677

Heat Exchanger: Replaces OEM part numbers 17118666811 and 17115A54040

Features:

6061-T6 aluminum construction eliminates weak plastic end tanks Dual-row core design for increased cooling capacity and efficiency Radiator: 42mm dual-row core (45% thicker than OE 34mm core) Heat Exchanger: 42mm dual-row core (72% thicker than OE 25mm core) TIG-welded end tanks for superior strength and reliability Polished aluminum finish for a premium, high-performance look CNC-machined connectors and brackets for perfect OE fitment Fully compatible with factory hoses, fan shroud, condenser, and intercooler Direct bolt-in installation—no modifications required

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

Mishimoto E46 Aluminum Radiator features -

  • All aluminum construction
  • More durable and longer lasting than plastic components
  • 20% more capacity in the same space
  • Excellent fit and finish
  • Unbeatable lifetime warranty and accident-forgiveness

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!

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.

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 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).
