CSF High-Performance Radiator for E6x BMW M5 / M6 [7218]

CSF High-Performance Radiator for E6x BMW M5 / M6 [7218]

The E60 M5 and E6X M6 gained widespread acclaim in the mid-2000s for their 5.0L V10 engines and bold styling. These models remain highly sought after, celebrated for their future classic potential and distinction as the only BMWs ever equipped with V10 engines. Given current automotive trends, it is unlikely an engine like the S85 will ever appear in a production car again. While the factory radiator performs adequately, obtaining replacements can be challenging, and the immense heat generated by the V10 places significant stress on the cooling system. Upgrading to a larger, more efficient radiator enhances overall system longevity and ensures reliable performance in demanding conditions. This upgrade is especially critical for vehicles equipped with supercharger systems.

Design and Engineering

• CSF, renowned for decades of expertise in crafting high-performance all-aluminum radiators, has built an industry-leading reputation for quality and innovation. With extensive knowledge of BMW’s high-performance cooling systems, it was only natural for CSF to receive requests for a solution tailored to the E60 M5 and E6X M6.

CSF vs OEM

• The factory radiator in the E60 M5 and E6X M6 is a solid all-aluminum unit that has proven fairly robust over time. However, as these vehicles age and are subjected to additional power upgrades, the factory radiator often struggles to keep up. This is especially true for owners running superchargers, where the added heat from forced induction and the heat exchanger mounted in front of the radiator push the system to its limits. With E6X models approaching 20 years old and entering the “future classic” phase, many owners are undertaking restorations and upgrades. Upgraded, efficient components become essential in these scenarios. CSF addresses these challenges with its advanced radiator, featuring a 2-row 42mm aluminum core. This design not only increases fluid capacity but also enhances heat dissipation capabilities. CSF’s exclusive B-Tube Technology improves heat transfer by approximately 15% compared to standard oval welded tubes. The radiator’s 6 additional rows of cooling tubes and multi-louvered fins maximize airflow and deliver performance far superior to the OEM unit. Designed for seamless installation, the CSF radiator mounts directly into the factory location without requiring modifications or cutting. Constructed with 100% TIG-welded all-aluminum materials, it offers enhanced durability and longevity, ensuring it can withstand the demands of hard driving conditions. Whether restoring or upgrading, the CSF radiator provides the reliability and performance these iconic vehicles deserve.

About CSF

Back in 1947, a father and his three sons embarked on a business venture by setting up a small retail shop dealing in automotive parts. The family business blossomed over the years, evolving into an automotive garage specializing in radiator repair, and later, a radiator manufacturing facility. By 1975, the family-owned brand CSF was established, marking a milestone as the first to introduce import applications into the American automotive aftermarket, in line with the influx of Honda, Datsun, and Toyota vehicles. By 2009, the fourth generation of the CSF family joined the business, which had by then become a leading name in the import and domestic radiator and condenser markets, selling over 650,000 units that year despite an economic recession, and totaling over 35 million units to date. CSF’s portfolio expanded to include a diverse range of cooling systems, including commercial trucks, industrial and agricultural applications, marine coolers, intercoolers, pressure caps, and a pioneering Racing & High Performance Division. Today, CSF’s Racing & High Performance Division is renowned for designing and manufacturing advanced, efficient, and reliable cooling systems for a wide array of applications, from high performance all-aluminum direct-fit radiators to custom systems for racecars, power sports, off-road, marine, and industrial use. With over 50 years of experience and more than 40 million cooling systems sold worldwide, CSF has rightfully earned the industry title of “THE COOLING EXPERTS.”
