The Honda Accord Euro CL is one of Honda's most capable and underrated performance platforms — a refined, front-wheel-drive sports sedan powered by the K-Series engine family. Whether you're running a stock K24A or building toward a more aggressive setup, the Koyorad KH081666 is a direct bolt-in performance upgrade that delivers improved cooling capacity without any cutting, drilling, or fabrication.
Also cross-references to the Acura TSX 2.4L MT (2004–2008) via part number KS081666. Koyorad's all-aluminium construction and high-efficiency 25mm core design dissipate heat faster and more effectively than the factory 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.
