CSF BMW S54 Swap Race-Spec Oil Cooler

If you're swapping an S54 engine into a BMW chassis like an E36 or E46, keeping oil temperatures in check is crucial, especially when you're pushing the car hard. This CSF S54 Swap Race-Spec Oil Cooler is designed to help manage those high oil temps. It's built to work with the factory S54 oil line connections, and CSF also offers a fitting kit for custom setups. This particular model is shorter on the right side, which is a smart design choice that allows you to keep your A/C lines routed in their original position, a common challenge with S54 swaps.

Even though this cooler is a bit more compact than some other CSF options, it offers similar performance thanks to its dual-pass design and eight cooling rows. The turbulated, heavy-duty bar and plate construction means it's well-built for reliable and durable operation. It's also designed to pair well with CSF's S54 Swap All-Aluminum Radiator, creating a robust cooling system for your swapped BMW.
