The CSF Dual-Pass Oil Cooler for Porsche 911 ('73 RS Style) is a high-performance cooling component designed to enhance oil temperature regulation. Constructed with custom end tanks featuring a 45-degree front angle, this oil cooler is engineered to fit flush inside '73-style RS bumpers, providing a seamless integration with the vehicle's aesthetic. Its dual-pass design improves heat dissipation by allowing oil to pass through the core twice, increasing cooling efficiency. The fittings are oriented straight back for straightforward installation, and the cooler can be mounted horizontally, vertically, or parallel to the ground, depending on airflow requirements. For optimal performance, CSF recommends modifying the front tub to facilitate better airflow, ensuring maximum cooling capacity during demanding driving conditions.
This oil cooler is suitable for Porsche 911 models from 1973, especially those configured with RS-style bumpers. It is intended for use in high-performance applications, including track days, spirited driving, or any scenario where maintaining optimal oil temperature is critical. The design allows for versatile mounting options to accommodate various installation setups, provided adequate airflow is achieved. The kit includes the oil cooler with custom end tanks and fittings, ready for direct installation. Proper airflow management and mounting are essential for achieving the best cooling performance, making this product an ideal upgrade for enthusiasts seeking reliable thermal management in their Porsche 911.

Overview
Overview
This Dual-Pass Oil Cooler can be mounted horizontally, vertically, as well as parallel to the ground (provided that the oil cooler has proper air-flow). The CSF #8201 Oil Cooler has custom end tanks with a 45' front angle, allowing it to fit flush inside '73-style RS bumpers. The fittings are pointed straight back. For best airflow and highest performance, CSF recommends cutting the front tub to allow for proper air flow, exiting behind the oil cooler and underneath the vehicle. Cutting the front tub will also give clearance to allow adding a rear fan shroud to pull more air through the cooler at slower speeds or while idling. In universal applications these oil coolers are commonly utilized for engine oil, transmission oil, power-steering fluid, and differential fluid, plus can be used as a water heat exchanger.The unique design of CSF's oil cooler line has distinct advantages over conventional style oil coolers (plate-type/stacked oil coolers). The oil coolers can be placed in tighter spaces or different areas of the vehicle that don't have much vertical surface area. Longer rectangular sizes can also help with avoiding the stacking of too many coolers which may cause airflow issues to other components in the cooling system. Inlet/outlet port placement is much easier to route oil lines. Typical oil cooler lines have to be routed from different/opposite ends of the cooler often facing up or down. Usually one line has to run across from one side of the cooler to the other to then be routed together to the feed/return connection of the oil system. The CSF oil coolers are much more robust, durable, and can withstand a higher peak burst rate. This allows the cooler to be mounted in areas that might get high debris (front fascia, diff cooler, side vents, etc…). The CSF oil cooler is designed to withstand a tremendous amount of vibration and debris.
