CSF 07-13 BMW M3 E9X High Performance Power Steering Cooler
Track-driven E9X M3's are known to have issues with stock power steering coolers. Due to the OE cooler's low efficiency, it's not uncommon for the system to overheat and cause a power steering fluid overflow out of the reservoir. If unchecked, this can cause power steering rack or pump damage.
This CSF power steering cooler differs in design over the OE cooler, a low-efficiency mechanically bonded core design, to the CAB-brazed high-efficiency plate-type design. It's made with CSF's AC condenser technology using a 1-row super-high pressure 18mm wide 4-channel microtube. It also offers a dual-pass 6-row design with an 83% increase in surface area compared to the OE unit. IT has been lab-tested at ~40% more efficient than OEM cooler
In addition to offering tremendous performance gains over the stock cooler, this CSF power steering cooler is a direct fit solution requiring no modifications to install. Accepts all attaching OE components including oil-line connections, mounting brackets, and AC condenser. World's 1st true "plug-and-play" power steering cooler for the E9X M3 platform.
- Increase in unit size (total 83 mm or 3.27 inches in height) designed towards the top of the cooler from OE position. This allows the cooler to work with any aftermarket supercharger heat exchanger or auxiliary coolers that may be placed underneath OE positioned power steering cooler.
