CSF Universal Single-Pass Oil Cooler / IROC Porsche / M22x1.5 / 24L x 5.75H x 2.16W

The CSF #8111 Universal Single-Pass Oil Cooler represents a meticulously engineered solution originally crafted for direct-fitment as a front mount center oil cooler specifically designed for Porsche 911/930 models produced up to 1989, particularly those equipped with IROC-style or similar front bumpers. This product’s dimensions and versatile mounting capabilities have enabled CSF to extend its application potential beyond the original scope, making it an ideal choice for a wide range of custom automotive installations.

The original equipment manufacturer (OEM) Porsche oil cooler has become increasingly scarce, with used RSR oil coolers commanding prices exceeding $3,000 USD in the resale market. CSF has effectively addressed this gap by offering a cost-effective alternative that incorporates advanced technology and superior fitment compared to the vintage original. The design improvements are evident in the tapered tank featuring a 15-degree inlet/outlet angle, which provides a significant enhancement over the bulkier banjo-style fittings that were standard more than three decades ago.

For those requiring a different configuration, CSF also offers a Dual-Pass version of the oil cooler with identical dimensions but with both oil connections positioned on a single end tank (CSF #8111). This flexibility allows for tailored integration depending on specific vehicle requirements or custom setups.

The innovative design of CSF’s oil cooler line offers several advantages over traditional plate-type or stacked oil coolers. These coolers are engineered to fit into tighter spaces or alternative vehicle locations where vertical surface area is limited. The elongated rectangular shape reduces the need for stacking multiple coolers, which can impede airflow to other critical components within the vehicle’s cooling system. Furthermore, the inlet and outlet port placement facilitates more straightforward routing of oil lines. Typically, oil cooler lines must be routed from opposite ends of the cooler, often requiring complex bends or crossing lines to reach the feed and return connections. CSF’s design minimizes these complications by positioning the ports adjacent to each other with a slight 15-degree angle, enhancing installation efficiency and reliability.

Durability and robustness are key attributes of the CSF oil cooler. It is constructed to withstand high peak burst pressures, making it suitable for installation in areas exposed to significant debris and vibration, such as front fascia, differential coolers, or side vents. This resilience ensures long-term reliability and consistent performance under demanding operating conditions.
