CSF 07-13 BMW M3 (E9X) High Performance Power Steering Cooler

The CSF High-Performance Power Steering Cooler for the 2007-2013 BMW M3 (E9X) is designed to keep power steering fluid temps under control, even during aggressive street driving or track sessions. While often overlooked, your power steering system takes a beating under high-performance conditions — overheating leads to sloppy steering response, pump noise, and premature fluid breakdown.

The engineers at CSF have applied their proven cooling expertise to solve that problem. This direct-fit cooler prevents fluid boil-over, maintains consistent steering performance, and helps avoid unnecessary repairs or fluid replacements. It’s a simple, must-have upgrade for keeping your E9X M3 sharp, responsive, and ready for hard driving.
