Description
The Mishimoto MMFS-WRX-01P is a direct-fit aluminum fan shroud engineered to bolt straight into the cooling system of the Subaru WRX and STI’s flat-four engine bay. Built from aircraft-quality TIG-welded aluminum with a brushed finish, it arrives pre-wired with factory-style pigtails so it plugs directly into your factory harness without any splicing. At its core sit two Mishimoto 12-inch slim electric fans, positioned to move air efficiently across the radiator core and help keep engine bay and coolant temperatures in check.
Beyond the plug-and-play electrical connection, this Mishimoto cooling upgrade is designed to work seamlessly with your existing setup. It’s compatible with the stock radiator, stock overflow tank, and factory fan plugs, and it also fits Mishimoto radiators, giving owners flexibility whether they’re keeping their factory setup or upgrading other cooling components. The shroud even includes provisions for mounting the factory coolant overflow bottle directly to it, streamlining installation and keeping the engine bay tidy. Every fan shroud kit ships with all necessary mounting hardware and is backed by the Mishimoto Lifetime Warranty.
Vehicle Applications
This fan shroud is a specific-fit part covering the 2002-2007 Subaru Impreza WRX, including WRX Limited trims for 2006-2007 and WRX TR trims for 2006-2007, along with the 2004-2007 Subaru Impreza WRX STI and the 2007 STI Limited. It also fits the 2005-2006 Saab 9-2X Aero. According to Mishimoto’s technical notes, this shroud pairs with vehicles using the EJ205, EJ255, and EJ257 engine codes and the GD8 chassis code. For 2002-2003 model year vehicles specifically, two additional plug adapters (P/N 45128FE000) may be needed from your dealership to complete the factory-style connection.
