Description
Koyo Performance Radiator – Honda Civic EG / EK (1991–2000)
Application: Honda Civic EG / EK | Multiple Chassis | Manual Transmission | Non A/C
Part Number: KV081225U06/ VH81226
The EG and EK Civic are two of the most iconic Honda platforms ever built — lightweight, nimble, and endlessly tuneable. Whether you're running a stock D-Series daily or a full B16/B16B track build, the factory radiator can become a limiting factor under sustained high-load conditions. The Koyorad KV081225U06 is a direct bolt-in performance upgrade engineered specifically for the EG and EK Civic, delivering improved cooling capacity without any cutting, drilling, or fabrication.
Koyorad's all-aluminium construction and high-efficiency 36mm 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.
⚠️ Fitment Note: This radiator requires removal of the factory air conditioning system for fitment. It will not fit vehicles equipped with A/C.
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.
