Koyo Performance Radiator – BMW M3 / M4 (F80/F82/F83) 2015–2020 / M2 Competition (F87) 2019–2020

Application: BMW M3 (F80) / M4 (F82/F83) / M2 Competition (F87) | S55B30T0 3.0L Twin-Turbo Inline-6 | Manual & M-DCT

Part Number: KV423704 / KL423704


The F80 M3, F82/F83 M4, and F87 M2 Competition are the definitive driver's BMWs of their generation — built around the S55B30T0 twin-turbocharged straight-six, a high-revving, high-output engine that generates serious heat under sustained performance driving. Whether it's a track day weapon, a spirited street car, or a dedicated circuit build, keeping coolant temperatures stable is critical to protecting the S55 and maintaining consistent power output.

Koyorad's all-aluminium radiator is a direct bolt-in performance upgrade for the F80/F82/F83/F87 platform, engineered to the same factory fit and mounting points as the OE unit. Nocolok furnace brazed, precision TIG welded by hand, and triple pressure tested — it retains all OEM fan shroud mounts and stock hose connections with no modifications required.


Why Koyorad?

  • Precise Tube & Fin Alignment — Strict quality control ensures optimal coolant flow and maximum heat transfer efficiency across the entire core.
  • Nocolok Furnace Brazing — All tubes, fins, headers, and brackets are bonded in a state-of-the-art Nocolok furnace, creating a structure that resists vibration, road debris, and the elements.
  • Billet Filler Neck — Precision-machined billet filler necks are fitted to every unit for superior strength, durability, and a reliable seal.
  • OE-Specific Mounting — Application-specific mounting points for fan shrouds, inlet/outlet hoses, and top/bottom pins ensure a pain-free, no-modification install.
  • Hand-Crafted Heliarc Welds — Each radiator is individually Heliarc welded by hand, creating the strongest possible aluminium-to-aluminium bond across all components.
