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

The CSF Universal Dual-Pass Oil Cooler, model #8201, represents a high-quality solution engineered for optimal thermal management in demanding automotive applications. Designed with versatility and performance in mind, this oil cooler can be mounted horizontally, vertically, or parallel to the ground, provided that adequate airflow is maintained. Its custom end tanks feature a precise 45° front angle, enabling a seamless fit inside the iconic '73-style RS Porsche bumpers, with fittings oriented straight back for streamlined installation.

To achieve the best airflow and maximize cooling efficiency, CSF recommends modifying the front tub by cutting it to allow air to flow properly through the cooler, exiting behind it and underneath the vehicle. This modification also facilitates the installation of a rear fan shroud, which enhances airflow through the cooler at lower speeds or while idling, ensuring consistent oil temperature regulation under various operating conditions.

In universal applications, this oil cooler is highly adaptable and commonly utilized for engine oil, transmission oil, power-steering fluid, and differential fluid cooling. Additionally, it can serve as a water heat exchanger, broadening its applicability across multiple vehicle systems.

The design of the CSF oil cooler line offers distinct advantages over conventional plate-type or stacked oil coolers. Its unique form factor allows installation in tighter spaces or vehicle areas with limited vertical surface area. The longer rectangular shape helps avoid stacking multiple coolers, which can impede airflow and negatively impact other components within the cooling system.

Furthermore, the inlet and outlet port placement simplifies the routing of oil lines. Unlike typical oil coolers that require lines to be routed from opposite ends—often facing up or down—CSF’s design allows for more straightforward line management, reducing complexity and potential points of failure. This design consideration enhances both installation efficiency and long-term reliability.

Constructed for robustness and durability, the CSF oil cooler withstands high peak burst pressures and is engineered to endure significant vibration and exposure to debris. This resilience makes it suitable for installation in areas prone to harsh conditions, such as front fascia, differential coolers, and side vents, ensuring reliable operation in demanding environments.
