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

The CSF #8110 Universal Dual-Pass Oil Cooler represents a significant advancement in oil cooling technology, originally engineered for direct-fitment as a front mount center oil cooler specifically tailored for Porsche 911/930 models produced up to 1989, particularly designed to integrate seamlessly with IROC-style or similar front bumpers. Recognizing its versatile dimensions and robust mounting options, CSF has expanded its application potential, making it an ideal solution for a broad range of custom automotive configurations.

The original equipment manufacturer (OEM) Porsche oil cooler, now exceeding 30 years in design age, has become increasingly scarce and difficult to source. The resale market for used RS oil coolers reflects this rarity, with prices often exceeding $3,000 USD. CSF addresses this gap by offering a technologically advanced, cost-effective alternative that not only matches but surpasses the fitment and performance of the original unit. Central to CSF’s design innovation is the tapered tank featuring a 15-degree inlet/outlet angle, a substantial improvement over the traditional bulky banjo-style fittings that were standard over three decades ago.

For those requiring a variation in flow design, CSF also offers a Single-Pass version of this oil cooler, maintaining identical core dimensions but featuring connections on opposing end tanks (CSF #8111), providing flexibility to meet diverse installation requirements.

The unique architecture of CSF’s oil coolers offers several distinct advantages compared to conventional plate-type or stacked oil coolers. Their compact and elongated rectangular form factor allows installation in tighter or unconventional spaces within the vehicle, particularly where vertical surface area is limited. This design also mitigates airflow obstruction issues commonly caused by stacking multiple coolers, thereby enhancing overall cooling system efficiency. Furthermore, the strategic placement of inlet and outlet ports on the same side facilitates more straightforward routing of oil lines. Traditional oil coolers often necessitate routing lines from opposite ends, sometimes requiring complex crossovers that complicate installation and maintenance. CSF’s configuration simplifies this process, reducing potential points of failure and improving system reliability.

Constructed with durability and resilience in mind, CSF oil coolers are engineered to withstand high peak burst pressures, making them suitable for installation in locations exposed to significant debris and vibration, such as front fascia areas, differential coolers, or side vents. This robustness ensures consistent performance and longevity even under demanding operating conditions.
