CSF Universal Single-Pass Oil Cooler / RSR Porsche / M22 x 1.5 / 22L x 4.75H x 2.16W

The CSF Universal Single-Pass Oil Cooler, model #8202, is engineered to provide exceptional cooling performance and versatility for a wide range of automotive applications. Designed with precision and durability in mind, this oil cooler is suitable for horizontal, vertical, or parallel-to-ground mounting positions, provided there is adequate airflow. Its custom end tanks feature a 45° front angle, enabling a perfect flush fit within the ’73-style RSR Porsche bumpers, with fittings oriented straight back for streamlined installation. To maximize airflow and optimize cooling efficiency, CSF recommends modifying the front tub to allow air to pass freely behind the cooler and exit beneath the vehicle. This modification also facilitates the addition of a rear fan shroud, which enhances air circulation through the cooler during low-speed operation or idling conditions. The versatility of this oil cooler extends beyond engine oil applications; it is commonly utilized for transmission oil, power steering fluid, differential fluid, and can also function effectively as a water heat exchanger in universal setups. The innovative design of the CSF oil cooler distinguishes it from conventional plate-type or stacked oil coolers. Its compact, elongated rectangular form factor allows installation in confined spaces or vehicle areas with limited vertical clearance, thus providing greater flexibility in placement. This design helps avoid the complications associated with stacking multiple coolers, which can impede airflow to other critical cooling system components. Furthermore, the inlet and outlet ports are strategically positioned to simplify oil line routing, eliminating the need for lines to cross over the cooler, which is a common challenge with traditional designs. Constructed with robust materials and engineered for high durability, the CSF oil cooler withstands elevated peak burst pressures, making it suitable for installation in areas exposed to debris and vibration, such as front fascias, differential coolers, and side vents. This resilience ensures reliable performance under demanding conditions, maintaining system integrity and extending service life.
