The CSF Oil Cooler Single-Pass for the Porsche 911 ('73 RS Style) is a high-performance cooling component designed to effectively manage engine oil temperatures. Constructed with custom end tanks featuring a 45-degree front angle, this oil cooler is engineered to fit flush inside '73-style RSR bumpers, providing a seamless integration with classic Porsche aesthetics. Its single-pass design ensures efficient heat dissipation, while the straight-back fittings facilitate straightforward installation. The cooler's versatile mounting options—horizontal, vertical, or parallel to the ground—allow for flexible placement based on airflow and space constraints. For optimal performance, CSF recommends modifying the front tub to enhance airflow, directing hot air behind the cooler and underneath the vehicle, which maximizes cooling efficiency during demanding driving conditions.
This oil cooler is suitable for a range of Porsche 911 models from 1973 onwards, particularly those seeking improved oil cooling for track days, spirited driving, or high-performance applications. It is designed as a direct replacement or upgrade for stock oil cooling systems, offering enhanced durability and thermal management. Installation involves cutting the front tub for airflow optimization, with fittings pointed straight back for secure connections. The kit includes the oil cooler with custom end tanks and fittings, ensuring a precise fit and reliable operation. Ideal for enthusiasts looking to maintain optimal oil temperatures under high-stress conditions, this cooler provides a robust solution for both street and track use.

Overview
Overview
This Single-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 #8202 Oil Cooler has custom end tanks with a 45' front angle, allowing it to fit flush inside '73-style RSR 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.
