Description
Design & Engineering
In 2019, CSF "reinvented" a common yet critical item, with features and benefits never seen before on an aftermarket high-performance oil cooler. This cooler can be utilized for engine oil cooling, transmission oil cooling, power-steering, differential-cooling, and as a water/coolant heat exchanger.
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 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 oil coolers, but with vertically oriented inlet and outlet connections.
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 -16AN 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.
Aero-Flow Bar/Plate Core
The new oil cooler features CSF's unique "Aero-Flow" Bar Design. This core design offers weight savings over traditional bar/plate cores without sacrificing durability. CSF's proprietary design offers maximum oil and airflow through the core.

Inlet/Outlet Connections
The CSF #8371 uses the same M22 x 1.5 Inlet/Outlet connections as most of the CSF Oil Coolers. This thread pitch offers a huge variety of connection options while maintaining the best possible flow characteristics. With a nominal diameter of 22mm, the M22 x 1.5 threaded bungs are large enough to work with adapter fittings as large as -16AN. CSF also included two 1/8 NPT Ports on each tank for bleeding or temperature sensors.

Mounting Holes
All CSF Oil Coolers utilize a 3 hole mounting system on ends of the core. The position and orientation allows for a wide variety of mounting options. The M8 x 1.25 thread pitch offers more than enough tensile and sheeting strength for extreme durability and easy to source hardware.

The oil cooler can be clocked in any orientation for mounting. This oil cooler is used on the CSF Ford GT Transaxle Oil Cooler mounted in a sideways configuration. However, a vertical orientation with the inlet/outlets pointed up or down will be the most common use case for most universal applications.

CSF vs the Competition
CSF oil coolers are much more robust, durable, and can withstand a higher peak burst rate than common brazed plate-type/stacked designs. This allows the cooler to be mounted in areas that might get high debris (front fascia, diff cooler, side vents, etc). When using a conventional oil cooler, the type of mounting locations are often not considered due to the risk of damage. The CSF oil cooler is designed to withstand a tremendous amount of vibration and debris. You can even stand on it!
