The CSF units utilize a modern and robust tube and fin core specifically designed for this cooler. This new core has higher flow, less pressure drop, and is more durable than the original design. In addition to the upgraded core, CSF added support/strength bars between the tubes. These bars increase the burst pressure which has been tested to 290 psi (20bar) without leaking. The high-performance core uses 7 cooling tubes with 8 rows of fins. Between the ultra efficient fin design and high flow tubes, the CSF cooler is ~10% more efficient than a brand new OE unit and up to 25% more efficient than a used unit.

The O-Ring recesses are CNC milled into the billet for a perfect fit and seal. Nothing is worse than getting your engine put together only to find a minor oil leak at the O-Rings between the block and the oil cooler. You can now confidently install your oil cooler knowing you won’t get any leaks from improper O-Ring seating.

The machined in-house Stainless Steel fittings offer increased strength and durability over the OEM Aluminum slip-on tube (72-89 models) and threaded M30 fitting (65-71 models). Both OEM connections are common sources of leaks. CSF also includes two high quality copper crush washers to offer the best possible seal and prevent any leaks.
