CSF 11-16 BMW 135i(X) 5 Door F20 / M135i(X) 3 Door F21 Race-Spec Oil Cooler

Considering their expertise and success from other BMW cooling systems, CSF created yet another upgraded oil cooling system - this time for BMW's N55 engine. N55 powered BMWs have become popular among track and performance enthusiasts. With optimum oil temperatures maintained, drivers can dominate the track without the dreaded "cool down" or "limp mode" breaks.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.
