Unlike traditional stacked-plate coolers, CSF’s bar and plate design is engineered to withstand higher peak burst pressures and significant vibration, making it ideal for placement in high-debris areas like front fascias, side vents, or as a dedicated differential cooler.

This cooler features a long, rectangular 22-inch profile that helps avoid the common issue of stacking multiple heat exchangers, which can often restrict airflow to the radiator. The dual-pass configuration ensures maximum thermal exchange while keeping both -10 AN male ports on the same side, significantly simplifying oil line routing in tight engine bays. To protect against the elements and maximize heat dissipation, the core is finished in a specialized thermal-rejecting matte black powder coat.

Fits select 2007-2015 BMW 1 Series (1M/135i/135is), 3 Series (335i/335is/M3), and X1 xDrive35i models. This versatile unit serves as a high-performance DCT transmission cooler for the E9X M3 or a primary engine oil cooler for 6-speed manual equipped N54/N55 models.

The CSF 8042 is engineered as a true plug-and-play solution, utilizing CSF’s advanced AC condenser technology. Featuring a 22mm wide, 11-channel microtube core, this dual-pass design provides a significant thermal upgrade over the factory unit. Laboratory testing shows it is approximately 30% more efficient than the OEM cooler, thanks to a high-density multi-louvered fin design that offers 20% more surface area contact.

Designed for a seamless installation, this "Drop-in Fit" cooler requires no modifications and is compatible with all factory mounting points, oil-line connections, and plastic ducting/shrouds.

Fits select 2006-2013 BMW 128i, 325i/xi, 328i/xi, 330i/xi, and M3 models.

Maintain consistent steering response and prevent fluid boil-over during track days or spirited driving with the CSF high-performance power steering cooler. This unit addresses the shortcomings of the factory cooling system by replacing the low-efficiency, mechanically bonded OEM core with a robust CAB-brazed, plate-type design. Lab testing shows an approximate 40% increase in efficiency over the original unit.

Engineered for seamless integration, this cooler features a dual-pass, 6-row design with an 83% increase in surface area. The 83mm (3.27 in) core height is strategically shifted toward the top of the unit to provide additional clearance for aftermarket supercharger heat exchangers or auxiliary coolers. This makes it an ideal upgrade for forced induction builds or high-load track applications.
