This radiator features a robust 48mm aluminum core designed to significantly enhance cooling efficiency over stock units. It is specifically designed for manual transmission applications and utilizes 32mm inlet and outlet pipes for proper fluid flow. This HH Series radiator is compatible with Honda Civic models from 1992-2000, including the Civic Si, and Honda Civic del Sol models from 1993-1997.

It is always recommended to verify fitment for your specific year, model, and engine configuration.
