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.
