Performance Radiator for BMW 5 Series (2011-2016) 2.0L 3.0L 4.4L

High-Efficiency All-Aluminum Performance Radiator for 2011-2016 BMW 5 Series

What it Does: The Performance Radiator replaces the leak-prone factory heat exchanger on the 2011-2016 BMW 5 Series to maximize thermal dissipation and prevent catastrophic coolant loss under heavy operating loads.

The Stock BMW 5 Series Plastic Tank Vulnerability

Factory cooling systems on the F10 chassis rely on radiators built with composite plastic end tanks crimped onto an aluminum core via rubber gasket seals. Over repeated thermal cycles, aggressive operating pressures (often exceeding 1.4 to 2.0 bar), and elevated under-hood temperatures from forced-induction powerplants like the N20, N55, and hot-vee N63, the stock plastic embrittles. Micro-fissures routinely develop along the crimp seams and the upper radiator neck, causing sudden coolant dumping, thermal runaway, and expensive engine block or cylinder head warping.

The Engineering Solution

This upgraded performance unit eliminates failure-prone plastic entirely, utilizing heavy-duty, 100% TIG-welded aluminum end tanks fused to a dense, brazed aluminum tube-and-fin core. The increased fin density and optimized fluid passages accelerate heat rejection, counteracting heat soak during extended high-speed cruising or aggressive driving. Precision-fabricated inlet and outlet ports retain factory-style quick-disconnect geometry for a leak-free seal with OEM hoses. Directly replacing OEM part 17117612994, this radiator bolts into the stock core support mounts with zero chassis cutting or bracket modification required.
