Product Description

The S54 is arguably one of the greatest BMW motors of all time. Power delivery, balance, and sound are top notch. While it doesn't compare in power potential to newer turbo powered inline 6 motors, many enthusiasts still love and crave the NA power delivery that BMW was and still is famous for. Despite not being the most powerful option, the S54 Swap has become increasingly popular in the BMW community for the E36 Chassis.

Even though the swap is an easy "fit", the S54 swap does require quite a bit of work to get working an older BMW chassis. CSF has seen the struggle with the cooling system adaptations and now has a solution. Enter the CSF BMW S54 Swap Radiator and Oil Cooler for the E36 Chassis.

Design & Engineering

CSF's industry-leading reputation and deep knowledge of high-performance BMW cooling systems offered an edge when designing such a unique cooling system. Combining the experience from producing the best cooling systems for the E36 and E46, CSF was able to design and produce an innovative solution that covers the widest range of S54 swap customers possible.

Any who has ever tracked an E46 M3 or even just driven one hard knows how quickly the oil temperatures can climb. For the E46 M3, CSF developed the Dual Pass Race Spec Oil Cooler (CSF #8032) with Rogue Engineering. This has been the go to solution for the E46 M3 community and will work on S54 Swaps when paired with this radiator. Why are there two oil coolers then you might ask? Because of the chassis differences, the CSF #8032 will not allow owners to retain air conditioning with their S54 Swap.

Enter the new CSF S54 Swap Race Spec Oil Cooler. This new oil cooler is shorter on the right hand side allowing owners to run the A/C lines in the OEM path. Even though the #8240 is slightly smaller than the #8032, you can expect similar performance levels as they both feature a dual pass design with 8 cooling rows and are the same turbulated heavy-duty bar/plate construction.

Both oil coolers utilize the S54 OEM oil line connections. However, CSF also offers a fitting kit with -10 AN hookups (CSF #8241) for customers looking to run custom oil lines.

Fitting Adapters

CSF offers a fitting adapter kit for -10 AN Oil Lines (CSF #8241). AN lines are a very popular and common upgrade for engine swaps. Offering this fitting makes the installation process easier and provides additional options for customers and installers.
