Mishimoto’s aluminum radiator for 2002–2005 Honda Civic Si (EP3) replaces the stock unit with a two-row, 1.42-inch brazed-aluminum core and polished end tanks to improve cooling efficiency and longevity. Full-aluminum construction with TIG-welded end tanks increases heat and pressure tolerance. The radiator includes a 1.3 bar high-pressure cap to raise coolant boiling point and is backed by Mishimoto’s limited lifetime warranty.
