It uses a two-row, 1.97-inch-thick brazed aluminum core to raise cooling efficiency by up to 30 percent, with full aluminum construction and durable TIG-welded end tanks. Installation is a direct OEM fit with no cutting or modification, and a 1.3-bar high-pressure Mishimoto radiator cap is included.
