CSF 8201 Dual Pass Oil Cooler for PORSCHE 911 ('73 RS Style)

This dual-pass oil cooler can be mounted horizontally, vertically, and also parallel to the ground (provided the oil cooler has adequate airflow). The CSF #8201 oil cooler features custom 45' angled front end tanks, allowing it to sit flush with the bumpers of a '73 RS. The fittings are directed straight back. For optimal airflow and maximum performance, CSF recommends cutting the front valance to allow proper exit airflow behind the oil cooler and under the vehicle. Cutting the front valance also allows for the installation of a rear fan shroud to pull more air through the cooler at low speeds or idle. In universal applications, these oil coolers are commonly used for engine oil, transmission oil, power steering fluid, and differential fluid, and can also be used as a water-to-oil heat exchanger. CSF's unique tube-fin oil cooler design offers distinct advantages over traditional tube-and-fin or stacked-plate oil coolers. Oil coolers can be mounted in tight spaces or in various locations on the vehicle where there is not a large vertical surface area. The longer rectangular dimensions also help avoid installing too many coolers, which can cause airflow issues for other cooling system components. The placement of the inlet/outlet ports significantly eases oil line routing. Typically, oil cooler lines have to be routed from opposite ends of the cooler, often pointing up or down. Usually, one line has to travel from one side of the cooler to the other to then connect to the oil system's supply/return port. CSF oil coolers are far more robust, durable, and can withstand higher peak flow rates. This allows the cooler to be mounted in locations where a lot of debris may enter (front valance, diff cooler, side vents, etc.). The CSF oil cooler is designed to withstand a tremendous amount of vibration and debris.
