CSF is one of the premier cooling product specialists available on the market today. One item that is often overlooked is the power steering. Luckily CSF has taken up the task of upgrading the oil cooler as well. If the power steering fluid gets too warm, it could lead to excess strain and wear to the steering rack. This unit has 6 cooling cores and still fits in the stock location without any issues.

2006-2012 E9X BMW 325i/xi 328i/xi 330i/xi M3
