Manage engine oil temperatures under extreme track or endurance conditions with the CSF Race-Spec Oil Cooler. This innovative cooling solution utilizes a dual-core in-series system, incorporating CSF's AC condenser technology with 26mm multi-channel microtubes. By adding five additional rows of cooling on the rear side of the unit, this cooler provides an approximate 40% increase in heat rejection over the factory component.

Designed as a true plug-and-play upgrade, the 8145 features a single-pass design with a high-pressure return line for optimal flow. It maintains a "drop-in fit" that requires no modifications to the vehicle, accepting all factory mounting brackets, oil-line connections, and ducting. This unit was track-tested and proven on the Hittman Racing M235iR endurance race car.
