CSF Universal Internal/External Dual-Pass Oil Cooler 

The CSF BOSS Universal Oil Cooler is a high-performance cooling solution designed for custom, racing, and resto-mod applications. Engineered for both internal and external mounting, its versatile universal design allows installation on virtually any vehicle while delivering exceptional cooling efficiency and durability.

Built with a heavy-duty bar-and-plate construction, the BOSS Cooler is designed to withstand harsh environments, including high vibration and debris-prone mounting locations. The dual-pass, turbulated core maximizes heat dissipation and cooling performance, while the compact rectangular design allows installation in tighter spaces where conventional oil coolers may not fit.

Unlike traditional stacked-plate coolers, the CSF design offers simplified oil line routing with convenient inlet and outlet placement, reducing installation complexity and improving packaging flexibility.
