Product Details
The CSF Universal RS-Style Dual-Pass High-Performance Oil Cooler (8110) is a premium cooling solution engineered for classic Porsche performance applications, custom motorsport builds, and high-output street and track vehicles. Featuring CSF's advanced Aero-Flow bar/plate construction, a 10-row dual-pass cooling core, M22 x 1.5 fluid connections, and a protective satin black finish, this oil cooler delivers exceptional durability and efficient heat-transfer capabilities.
Originally developed as a front-mounted center oil cooler for Porsche 911 and 930 models through 1989 equipped with IROC-style or similar front bumpers, the CSF 8110 combines classic RS-inspired fitment with modern cooling technology. Its design offers a practical alternative to increasingly difficult-to-source original Porsche RS oil coolers while providing the flexibility required for custom installations.
One of the defining features of the CSF 8110 is its dual-pass cooling configuration. Unlike a single-pass cooler that directs oil through the core once, the dual-pass design routes fluid through two sections of the heat exchanger before returning it to the engine. This arrangement increases the fluid's travel distance through the core, providing additional opportunities for heat dissipation.
The CSF 8110 incorporates 10 rows of high-pressure bar/plate oil cooling, providing a rugged construction designed to withstand the vibration, pressure, and environmental demands of high-performance driving. Its elongated rectangular profile offers a substantial cooling surface while maintaining a relatively low vertical height.
The cooler features a large core measuring approximately 21.5 inches long, 5.75 inches high, and 2.25 inches thick, making it particularly suitable for front bumper openings and custom installations where a wide, low-profile cooling assembly is preferred.
CSF's proprietary Aero-Flow bar design is engineered to improve fluid flow and heat transfer while maintaining excellent structural strength. Compared with conventional stacked-plate oil coolers, this construction provides a robust alternative for applications where durability and cooling efficiency are priorities.
Another important feature is the same-side inlet and outlet configuration. Both fluid connections are located on one end of the cooler, simplifying hose routing in applications where the oil supply and return lines approach from the same side of the vehicle.
The connections are incorporated into specially designed tapered end tanks with a 15-degree fitting angle, providing additional clearance in tight front bumper installations. This design is particularly beneficial for Porsche IROC-style bumper configurations, where traditional bulky fittings can create installation challenges.
The CSF 8110 features M22 x 1.5 female-threaded inlet and outlet ports, allowing the use of compatible M30, -16AN, and -12AN adapter configurations. These options provide flexibility when integrating the cooler into factory-style Porsche plumbing or custom AN hose systems.
For secure mounting, the cooler incorporates triangular flush-mounting provisions with M8 x 1.25 threaded holes. These attachment points allow fabricators to design mounting brackets appropriate for the vehicle and installation location.
The satin black finish provides a clean, motorsport-inspired appearance while helping protect the cooler's exterior against corrosion and road debris.
With a 0.89-liter (0.94-quart) fluid capacity and manufacturer pressure testing at 120 PSI, the CSF 8110 offers a substantial cooling solution for performance vehicles operating under demanding conditions.
Beyond its original Porsche application, the cooler's universal design makes it suitable for custom Honda, Acura, BMW, Mitsubishi, and other performance builds when properly sized and installed.
Whether restoring a classic Porsche RS-style cooling system, building a turbocharged K-Series Honda, or fabricating a dedicated motorsport oil cooling package, the CSF 8110 combines advanced cooling technology, durable construction, and versatile installation capabilities.

Dual-Pass Oil Cooling Design
The CSF 8110 utilizes a dual-pass configuration that directs engine oil through two sections of the cooling core before returning it to the lubrication system.
This arrangement increases the distance oil travels through the heat exchanger, providing additional opportunities for heat transfer.
The same-side inlet and outlet arrangement can also simplify plumbing by keeping the oil supply and return connections together.
Actual cooling performance depends on oil flow, airflow, ambient conditions, and the complete lubrication system.
Aero-Flow Bar/Plate Core Technology
CSF's Aero-Flow bar/plate construction is designed to provide a balance of cooling efficiency, fluid flow, and structural durability.
The core uses internal fluid passages and external cooling surfaces to transfer heat from circulating engine oil to surrounding airflow.
Its 10-row design provides a substantial heat-transfer surface while maintaining a relatively compact vertical profile.
The bar/plate construction also provides a rugged alternative to conventional stacked-plate coolers in applications exposed to vibration and road debris.
Porsche RS-Style Front Center Oil Cooler Design
The CSF 8110 was developed as a modern alternative for classic Porsche front-center oil cooler installations.
Original Porsche RS-style coolers can be difficult to source, particularly for older restoration and motorsport projects.
CSF designed the 8110 with modern bar/plate construction and specially angled fluid connections to improve installation flexibility.
Its 15-degree tapered connection arrangement helps reduce the clearance requirements associated with bulky traditional fittings.
This makes it particularly attractive for Porsche 911 and 930 vehicles equipped with compatible IROC-style front bumpers.
Important: A compatible bumper does not automatically guarantee that every hose, bracket, or fitting will transfer directly from an existing installation.
M22 x 1.5 Fluid Connections
The CSF 8110 features M22 x 1.5 female-threaded inlet and outlet connections.
These ports allow the use of compatible adapters for several plumbing configurations.
M30 Adapter Configuration: Suitable for appropriately configured Porsche-style oil plumbing.
-16AN Adapter Configuration: Provides compatibility with custom high-flow AN oil hose systems.
-12AN Adapter Configuration: Offers an alternative for custom applications requiring smaller AN hose connections.
Important: The cooler does not feature native male AN flare connections. Appropriate M22 x 1.5 adapter fittings must be selected separately.
Same-Side Inlet and Outlet Configuration
Both fluid connections are located on the same end of the CSF 8110.
This configuration is particularly useful when the oil supply and return lines approach from one side of the vehicle.
Compared with coolers featuring connections on opposite ends, the same-side arrangement may reduce the amount of additional hose routing required.
This can be beneficial in tight engine bays, front bumper installations, and custom motorsport applications.
Mounting Provisions
The CSF 8110 incorporates triangular flush-mounting provisions with M8 x 1.25 threaded holes.
These mounting points provide options for fabricating secure installation brackets.
The cooler should be mounted to prevent excessive movement, vibration, or stress on the fluid connections.
Proper clearance should be maintained from surrounding body panels, exhaust components, suspension parts, and other heat-sensitive components.
Oil Temperature Management
High-performance engines can generate significant oil temperatures during sustained high-load operation.
Elevated oil temperatures can reduce oil viscosity and place additional demands on the lubrication system.
A properly sized external oil cooler can help dissipate excess heat and support more consistent operating temperatures.
For street-driven vehicles, a thermostatic oil control system may be beneficial to prevent excessive cooling during normal operation.
Fluid Capacity and Oil System Requirements
The CSF 8110 has an internal fluid capacity of approximately 0.89 liters, equivalent to 0.94 quarts.
This additional volume must be considered when calculating the total oil capacity of the completed system.
Oil lines, adapters, and any remote filter components may further increase system capacity.
After installation, the lubrication system must be properly filled, primed, and checked for leaks before normal operation.
Factory Pressure Testing
CSF pressure-tests the cooler at 120 PSI during manufacturing.
This test is intended to verify the integrity of the cooling assembly.
It should not be interpreted as a universal maximum continuous operating pressure rating for every application.
Always verify that the cooler, fittings, hoses, and other components are suitable for the intended operating conditions.
