CSF 8110 RS-Style Dual-Pass Oil Cooler - M22 x 1.5 - 24in x 5.75in x 2.25in

Fits 1964-1989 Porsche 911 and 930 models equipped with IROC-style or similar front bumpers; also suitable for universal applications where space is limited.

The CSF 8110 RS-Style Oil Cooler utilizes a high-efficiency 10-row bar-and-plate design, offering significantly greater durability and pressure resistance than traditional stacked-plate coolers. This robust construction makes it an ideal choice for mounting in high-debris areas such as front fascias, side vents, or as a differential cooler. The dual-pass internal flow maximizes heat transfer by forcing oil through the core twice before exiting.

Designed for clean installations, the cooler features same-side M22 x 1.5 female inlet/outlet ports angled at 15 degrees. This configuration eliminates the need to route long return lines across the face of the cooler, improving airflow to the rest of the cooling system and simplifying plumbing in tight engine bays.
