This fuel injector was factory-issue on the 2006-2014 WRX and 2008-2021 STI models. Commonly referred to as the Subaru blue injector, it's a popular upgrade for older top feed-style cars like the 2002-2005 WRX.
ECU tuning will be required on cars that did not come with these injectors.
Sold individually.
Fits all 2006-2014 Subaru WRX, 2007-2021 WRX STI, and 2009-2013 Forester XT.
