Koyo (Koyorad) Performance Radiator: Honda / Acura Integra DC2 K-Series Swap 1994-2001

Koyo Performance Radiator – Honda / Acura Integra DC2 K-Series Swap MT (1994–2001)

Application: Honda / Acura Integra MT | DC2 | K-Series Swap (K20A / K24) | Manual Transmission

Part Number: KV081255U06 | SKU: V081255

The DC2 Integra is one of the most popular K-Series swap platforms in the world — lightweight, well-balanced, and a natural fit for the high-revving K20 or torquey K24. Once you've dropped in a K-Series, the factory radiator simply isn't up to the task. The Koyorad KV081255U06 is purpose-built for this exact application, delivering the cooling capacity your K-Swap needs 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 OEM-style mounting 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 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.
