CSF BMW M3 E90/E92/E93 Race Spec Engine Oil Cooler

High oil temperatures cause engine oil to deteriorate prematurely - a genuine concern during prolonged track sessions or hard driving on the E9X M3. CSF's Race Spec Engine Oil Cooler addresses this directly, engineered to keep oil temperatures consistently within a safe operating range rather than letting them climb unchecked during extended hard use.

A turbulated, heavy-duty bar/plate design delivers 8 rows of maximum cooling with a high-density, multi-louvered fin pitch, replacing the OEM's weaker mechanically-jointed and tack-welded end tanks with a fully TIG-welded cast-end tank design for genuinely superior reliability and durability. The tapered cast-end tank shape fits precisely within the contour of the OEM bumper - meaning it's also the only cooler on the market for this platform that requires no cutting of the shroud, and creates no fitment conflicts with aftermarket splitters either. It's a true drop-in fit, accepting all OEM oil-line connections, mounting brackets, and shroud/ducting.

Important: cars built before March 2008 use an earlier oil line spec - BMW superseded these on later vehicles, and this cooler is designed for the later-spec lines. Confirm which lines your car has, or budget for a lines/O-ring update, before ordering.
