Koyo Performance Radiator – Honda Civic EG / CR-X B16A MT 1991–1995

Application: Honda Civic (EG6 / EG9) & CR-X (EG2) | B16A | Manual Transmission | 1991–1995

The EG Civic and CR-X are cornerstones of Honda's performance heritage — lightweight, naturally aspirated machines built around the rev-happy B16A that remain a favourite for track days, time attack, and street builds worldwide. Whether you're running a stock B16A or a built motor with supporting modifications, keeping coolant temperatures in check is fundamental to consistent performance and engine longevity.

Koyorad's all-aluminium KH080300U06 is a direct bolt-in performance upgrade engineered specifically for manual transmission EG Civic and CR-X models. 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.
