CSF Universal Dual-Pass Oil Cooler with M22 x 1.5 Connections – 22" x 4.75" x 2.16"
For drivers seeking consistent oil temperatures during extended track sessions or demanding street drives, the CSF 8201 stands out as the practical solution that delivers sustained performance where others fall short. Built with a bar-and-plate construction that handles intense vibration and debris exposure better than stacked plate designs, this cooler maintains lower operating temps by up to 30% more effectively in real-world tests compared to standard single-pass units.
Its dual-pass flow path ensures thorough heat dissipation, making it the go-to option for enthusiasts who prioritize longevity and efficiency over basic cooling setups. Whether upgrading a classic air-cooled Porsche or fabricating a custom install on modern builds, the 8201 integrates seamlessly, providing the cooling capacity needed to keep your engine running cooler and more reliably lap after lap.
Key Specifications and Features
- Core Dimensions: 18.9" Length x 4.72" Height x 2.25" Width (overall unit: 22" L x 4.75" H x 2.16" W)
- Construction: Heavy-duty aluminum bar-and-plate design with black powder coat finish for corrosion resistance
- Connections: M22 x 1.5 female inlet and outlet ports, oriented straight back for simplified hose routing
- Flow Design: Dual-pass configuration for maximum heat exchange efficiency
- Mounting: Triangular flush mounting holes; supports horizontal, vertical, or parallel installation with unobstructed airflow
- End Tanks: Custom-molded with 45-degree front angle for compact fit in tight spaces like front fascias or side vents
- Applications: Handles engine oil, transmission fluid, power steering, differential oil, or serves as a water-to-oil heat exchanger
- Durability: Rated for higher burst pressure (up to 500 PSI) and built to withstand high-vibration environments without cracking or leaking, outperforming tube-and-fin alternatives in long-term reliability tests.
This setup avoids common pitfalls of bulkier coolers, such as airflow blockage to radiators or restricted line paths, ensuring your entire cooling system performs at its peak without compromises.
Vehicle Fitment Details
The CSF 8201 is a universal cooler designed for broad compatibility, but it excels as a direct bolt-in for specific setups:
- Porsche 911 (1973 Models with RS/RSR-Style Front Bumper): Perfect drop-in replacement for modified front oil cooler applications fits flush inside '73-style RS bumpers without fabrication. Compatible with air-cooled 911 variants equipped for front-mount cooling.
- Universal Applications: Ideal for any vehicle requiring a compact, high-capacity oil cooler, including custom race cars, off-road builds, or performance-modified imports/domestics. Requires minor fabrication for non-direct-fit installs, such as custom brackets or hose adapters.
- Year Range: 1973+ for Porsche-specific fit adaptable to 1960s-2020s models across makes like BMW, Subaru, Ford, or Chevy with similar space constraints.
Always verify clearance and airflow paths for your exact setup CSF recommends pairing with a SPAL fan shroud for low-speed cooling boosts.
What's Included in Your Purchase
Every CSF 8201 kit comes complete and ready for install:
- One (1) Universal Dual-Pass Oil Cooler (Part Number: 8201)
- Pre-assembled M22 x 1.5 fittings (no additional adapters needed for standard AN lines)
- Mounting hardware: Stainless steel bolts and triangular bracket tabs for secure flush mounting
- Installation guide: Digital flyer with diagrams for Porsche RS fitment and general universal tips
No additional components like hoses, fans, or brackets are included—pair with CSF's optional shrouds (e.g., #8202) for full-system integration.
Packaging and Shipping Details
- Part Weight: 8 lbs (net weight for easy handling during install)
- Shipping Box Dimensions: 24" L x 7" W x 5" H
Why Choose the CSF Over Alternatives?
In head-to-head comparisons on forums and dyno sheets, the 8201 consistently drops oil temps 20-40°F lower than comparable Setrab or Mocal units of similar size, thanks to its bar-plate efficiency and vibration-proof build.
Users report zero failures after 50,000+ miles of abuse, from Le Mans-style endurance races to daily canyon carving far exceeding the service life of cheaper stacked-plate options that warp under heat cycles. For Porsche 911 owners chasing that authentic RS cooling without the OEM fragility, or fabricators needing a bulletproof universal piece, this is the component that pays off in every revved-out mile.
