Ultimate Cooling for Your N55 BMW

When pushing your BMW M2, M235i, or 335i/435i to the limit, factory cooling systems often fall short. The CSF High-Performance All-Aluminum Radiator (CSF7078) is engineered to provide maximum thermal efficiency for both street-driven performance builds and dedicated track cars. With over 50 years of cooling expertise, CSF delivers a direct-fit solution that replaces fragile plastic end-tank units with a robust, all-aluminum construction.

Advanced B-Tube Technology

This radiator features CSF’s proprietary B-Tube technology. Unlike standard oval-shaped tubes, these B-tubes are specially engineered and brazed to create a stronger, more efficient heat exchanger. This design allows for:

• Increased surface area for superior heat dissipation
• Thinner, lighter aluminum material without sacrificing structural integrity
• Improved coolant flow and pressure resistance
• Direct drop-in fitment for F87 and F3x chassis

Whether you are dealing with high-horsepower tuning or intense heat soak during track days, this radiator ensures your engine stays within optimal operating temperatures. Its 2-row core provides significantly more cooling capacity than the OEM unit, preventing power loss caused by high intake temperatures and engine heat. Trust the cooling experts at GGCRACING to keep your BMW running at its peak performance level.
