The CSF Universal Dual-Pass Internal/External Oil Cooler is a heavy-duty bar-and-plate cooler built for durability in internal or external mounting. Its flippable universal design lets the inlet/outlet sit on either side, with -10AN male connections and a turbulated 8-row core using a high-density multi-louvered fin pitch. A semi-gloss/matte black thermal-rejecting powder coat resists heat and corrosion, and two M8 mounting bosses with steel helicoils provide secure attachment.
