CSF BMW F3X / F2X (N55) Race-Spec Oil Cooler

CSF, a recognized leader in automotive cooling technology, has developed the Race-Spec Oil Cooler specifically engineered for BMW's N55 engine series. Building on their extensive experience and proven success with BMW cooling solutions, CSF presents an advanced oil cooling system designed to meet the rigorous demands of track and performance driving. This product is tailored to maintain optimal oil temperatures, thereby enhancing engine reliability and performance during extended high-stress operation.

The N55 engine, a turbocharged 3.0L inline-six, powers a variety of BMW models favored by enthusiasts who seek both everyday drivability and track capability. The CSF Race-Spec Oil Cooler ensures that oil temperatures remain within ideal parameters, effectively preventing the common issues of overheating that can lead to engine "limp mode" or forced cooldown periods. This allows drivers to maximize their vehicle’s potential without compromise.

Key Features

• Innovative 2-Core In-Series System: This dual-core configuration enhances cooling efficiency by increasing the surface area for heat dissipation, ensuring superior thermal management under demanding conditions.
• Secondary In-Series Backside Cooler: Equipped with an additional 5 rows of cooling fins, this component delivers a 40% increase in heat rejection compared to standard coolers, significantly improving overall system performance.
• Advanced AC Condenser Technology: Utilizes a 1-row, super-high pressure 26mm multi-channel microtube design, derived from CSF’s expertise in AC condensers, to optimize fluid flow and heat transfer.
• High-Density Multi-Louvered Fin Design: Maximizes surface area contact with airflow, enhancing cooling capacity while maintaining a compact form factor suitable for OEM fitment.
• Single-Pass Design with High Pressure Return Line: This configuration ensures optimal oil flow rates and pressure stability, contributing to consistent engine lubrication and cooling.
• Direct "Drop-In Fit" Installation: Designed to replace the OEM oil cooler seamlessly, requiring no modifications. It accepts all original mounting brackets, oil-line connections, and shroud/ducting components, facilitating straightforward installation.
• World’s First True "Plug-And-Play" Upgrade for BMW N55 Engines: This unique product offers a direct performance enhancement without the need for custom fabrication or additional parts.
• Track-Tested and Proven: Extensively validated by Hittman Racing’s M235iR endurance race car, demonstrating reliability and performance under extreme racing conditions.
• Oil Capacity Adjustment: Requires an additional half quart of oil during installation to ensure proper fill levels—OEM cooler capacity is 7 quarts, while the CSF Race-Spec Oil Cooler requires 7.5 quarts.
