CSF Large Universal Single-Pass Oil Cooler

CSF’s first 6 oil coolers were designed to have many distinct advantages over conventional plate-type/stacked style oil coolers. The long shape allowed them to be placed in tighter spaces or different areas of the vehicle that don’t have much vertical surface area. Inlet/outlet port placement also made routing lines easier in many setups.

However, for this new racing oil cooler, CSF went with a more traditional inlet/outlet orientation. The new single pass design features the same High Efficiency & Rugged Durability Bar/Plate Core as our best selling line of universal oil coolers, but with vertically oriented inlet and outlet connections. This high performance oil cooler is designed for maximum flow, durability, and improved cooling efficiency.

Key Features:

• High Efficiency “Aero-Flow” Bar/Plate Core – Designed to be Lightweight, Durable, and offer Maximum Flow.
• TIG-Welded End Tanks – Stronger and more durable than the brazed construction, reducing the risk of leaks.
• Massive Fluid Capacity – This oil cooler offers a whopping 1.5L (1.6 qt) of increased Fluid Capacity.
• M22 x 1.5 Inlet/Outlet Connections – TIG-welded for extreme durability. Internal Radius for Maximum Flow and Optimized to also accept AN-16 Connections.
• Triangular Flush Mounting Holes – (M8 x 1.25) on top and bottom – Offers a wide variety of mounting options and easy fabrication of mounting brackets.

• Overall Dimensions (including fitting bosses): 12.0″ L x 9.85″ H x 2.36″ W (305mm x 250mm x 60mm)
• Core Dimensions: 9.25″ L x 9.33″ H x 2.16″ W (235mm x 237mm x 55mm)

FAQs

What does a single-pass oil cooler do?

A single-pass oil cooler allows engine oil to flow through the core once, helping reduce oil temperatures efficiently while maintaining consistent oil flow for performance applications.

Is this CSF oil cooler suitable for track or racing use?

Yes. That's exactly what we built it for. High-performance street cars, track day builds, drift cars, and full race cars; if your engine oil is getting too hot, this oil cooler fixes it. 

Can this universal oil cooler be used with custom setups?

Yes, the universal design and flexible mounting points make it suitable for a wide range of custom fabrication and performance vehicle applications.

Why is a high performance oil cooler important?

Once your oil gets too hot, it stops protecting your engine. A high performance oil cooler keeps oil temperatures down so your engine lasts longer and runs harder lap after lap.
