Utilizing CSF's AC Condenser technology, their innovative dual-core in-series system features an additional 5 rows of super-high pressure multi-channel micro-tubes on the rear side of the oil cooler. The high performance tube spec, along with the high-efficiency multi-louvered fin design allows for maximum surface area contact and an approximate 40% increase in heat rejection. The High-Performance Race-Spec Oil Cooler directly replaces the factory unit, easily bringing engine oil temperatures down to a consistent and manageable level, even under extreme & extensive driving conditions.
