Koyo Performance Radiator – Honda Civic Type R EP3 K20A MT (2001–2005)
Application: Honda Civic Type R MT | LA-EP3 | K20A | Manual Transmission
Part Number: KV081578R/ V2574
The EP3 Civic Type R is one of Honda's most celebrated front-wheel-drive hot hatches — a high-revving, naturally aspirated machine built around the legendary K20A engine. Whether you're running a stock build or pushing the EP3 hard on track, the factory radiator can become a limiting factor under sustained high-load conditions. The Koyorad KV081578R is a direct bolt-in performance upgrade engineered specifically for the EP3, delivering improved cooling capacity without any cutting, drilling, or fabrication.
Koyorad's all-aluminium construction and high-efficiency core design dissipate heat faster and more effectively than the factory unit, keeping coolant temperatures in check even under sustained high-load driving. 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.
