{"product_id":"fuel-injector-sub-assembly","title":"Fuel Injector Sub Assembly","description":"The Subaru 16611AA680 is a genuine fuel injector sub assembly, engineered as a direct replacement part for compatible Subaru models. This component is crucial for the proper functioning of your vehicle's fuel system. Each vehicle requires a set of four injectors for optimal performance. A failed fuel injector can lead to symptoms such as misfires, bucking, or hesitation under load, often accompanied by a check engine light.\n\nThis fuel injector sub assembly is compatible with various Subaru models, including the 2005-2010 Forester, 2005-2011 Impreza, 2005-2011 Impreza WRX, and 2005-2011 Impreza STI, all equipped with the 2.5L H4 engine. Installation typically involves relieving fuel system pressure, removing the fuel rail protector(s), disconnecting electrical connectors and fuel hoses, and then removing the fuel rail and injectors. It is important to replace the injector O-rings during installation. This part is also noted as being California emissions compliant.\n\n**Important Fitment Note:** While listed as compatible with 2005-2011 Subaru Impreza STI models, one source explicitly states that this part *does not fit* a 2005 Subaru STI. Buyers should verify fitment carefully for their specific vehicle configuration.","brand":"STI","offers":[{"title":"Default Title","offer_id":52663842308408,"sku":"16611AA680","price":113.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687715313.jpg?v=1784330084","url":"https:\/\/store.motormia.co\/products\/fuel-injector-sub-assembly","provider":"MOTORMIA","version":"1.0","type":"link"}
