CSF Universal Large Single-Pass Oil Cooler – M22 x 1.5 | 12 in. x 9.33 in. x 2.16 in. | High-Burst Tube-and-Fin Construction

The CSF Universal Large Single-Pass Oil Cooler is a high-performance, tube-and-fin construction oil cooler engineered for universal performance and motorsport applications — delivering superior durability, higher burst pressure resistance, and greater debris tolerance than conventional brazed plate-type or stacked plate oil cooler designs. With an M22 x 1.5 inlet/outlet thread, 12 in. x 9.33 in. x 2.16 in. core dimensions, and CSF's proven tube-and-fin construction, this is a large-format oil cooler suitable for high-output engines, differential cooling, transmission cooling, and other high-heat oil cooling applications where a robust, reliable cooler is required. The CSF oil cooler's construction allows it to be mounted in locations that conventional plate-type coolers cannot — front fascia, differential cooler positions, side vents, and other high-debris areas — without the risk of damage that limits conventional cooler placement options.

Key Features:

• Tube-and-fin construction — CSF's robust tube-and-fin design is significantly more durable and debris-resistant than conventional brazed plate-type or stacked plate oil cooler designs — can withstand higher peak burst pressure and greater vibration and debris impact
• High burst pressure resistance — engineered to withstand a higher peak burst rate than common brazed plate-type and stacked designs — correct for high-pressure oil systems and demanding mounting locations
• Debris and vibration tolerance — the tube-and-fin construction withstands significant vibration and debris impact — allowing mounting in front fascia, differential cooler, side vent, and other high-debris locations that are not suitable for conventional plate-type coolers
• M22 x 1.5 inlet/outlet — M22 x 1.5 threaded inlet and outlet ports — the most common oil cooler thread size for performance and motorsport applications — compatible with a wide range of sandwich plate adapters and AN fittings with the correct adapter
• Large format — 12 in. x 9.33 in. x 2.16 in. core — substantial cooling capacity for high-output engines, differential cooling, and other high-heat applications
• Single-pass design — oil flows through the cooler in a single pass from inlet to outlet — correct for applications where a single-pass flow path is required or preferred
• Universal fitment — no vehicle-specific mounting brackets — custom mounting fabrication required for installation
• CSF quality — manufactured by CSF, a respected US heat exchanger brand with a strong following in the performance and motorsport community

Why Tube-and-Fin vs. Plate-Type Oil Coolers?

• Burst Pressure Resistance: Brazed plate-type and stacked plate oil coolers are constructed from thin metal plates bonded together — a construction that is efficient for heat transfer but vulnerable to high burst pressure events (oil pressure spikes, cold start high-viscosity pressure) and debris impact. CSF's tube-and-fin construction uses individual tubes for oil flow with fins bonded between them — a construction that is inherently more resistant to burst pressure and debris impact. For high-pressure oil systems and demanding mounting locations, tube-and-fin construction is the correct choice.
• Debris Tolerance: Plate-type coolers mounted in high-debris locations (front fascia, differential cooler positions) are vulnerable to fin damage from road debris, rocks, and other impacts — damage that reduces cooling efficiency and can eventually cause leaks. CSF's tube-and-fin construction is significantly more resistant to debris impact — allowing the cooler to be mounted in locations that would damage a conventional plate-type cooler. CSF's own claim: you can stand on it.
• Vibration Resistance: High-vibration mounting locations (differential cooler, transmission cooler, engine bay) subject oil coolers to sustained vibration that can fatigue the bonded joints of plate-type coolers over time. CSF's tube-and-fin construction is engineered to withstand significant vibration without joint fatigue — maintaining structural integrity and leak-free operation over the long term.
• Mounting Flexibility: The combination of high burst pressure resistance, debris tolerance, and vibration resistance allows the CSF oil cooler to be mounted in locations that conventional plate-type coolers cannot — front fascia, differential cooler positions, side vents, and other high-debris, high-vibration areas. This mounting flexibility is a significant practical advantage in custom performance and motorsport builds where the ideal cooler location may not be a protected, low-debris area.

What's Included:

• CSF universal large single-pass oil cooler — M22 x 1.5 / 12 in. x 9.33 in. x 2.16 in. (CSF8371)
• Note: No mounting hardware, sandwich plate adapter, fittings, or fluid lines included — these must be sourced separately for your specific installation.

Installation Notes:

• Custom mounting bracket fabrication required — the CSF universal oil cooler does not include vehicle-specific mounting hardware. Design and fabricate mounting brackets appropriate for your specific vehicle and mounting location.
• Source the correct sandwich plate adapter (M22 x 1.5) for engine oil cooling applications, or the correct AN fittings and adapters for remote-mounted applications
• Route oil lines away from heat sources (exhaust, turbocharger) and sharp edges — use braided stainless AN lines with correct fittings for a durable, leak-free installation
• Install an oil thermostat in the oil cooling circuit if the cooler will be used in a street-driven vehicle — an oil thermostat prevents the oil from being overcooled in cold ambient temperatures, which can cause condensation and sludge formation in the oil system
• Verify that the cooler's mounting location provides adequate airflow for the cooler's heat rejection capacity — a cooler mounted in a low-airflow location will not perform to its rated capacity
• Pressure test the installation before returning the vehicle to service — verify that all fittings and connections are leak-free at operating pressure
