The Mishimoto X-Line Performance Aluminum Radiator is a thicker-core cooling upgrade engineered for the 2002-2007 Subaru WRX and STI (manual) and the 2005-2006 Saab 9-2X Aero. It uses a large three-row, 100% brazed aluminum core with TIG-welded end tanks for greater coolant capacity, durability and lower engine temperatures even under hard driving. The radiator includes a high-pressure 1.3-bar cap to raise the coolant boiling point, a second cap for the expansion tank, and a Mishimoto magnetic drain plug that captures metal fragments from the cooling system.
