{"product_id":"5300987-doser-injector-kit-for-cummins-isx-qsx-15l-new","title":"5300987 – Genuine Cummins Doser Injector Kit","description":"\u003cp data-end=\"1258\" data-start=\"372\"\u003eThe Genuine Cummins 5300987 Doser Injector Kit is an aftertreatment fuel doser injector used on select Cummins ISX\/QSX 15L engines. This component meters diesel fuel into the exhaust aftertreatment stream to support diesel particulate filter regeneration and emissions-system operation. It is not a main engine cylinder injector and should not be confused with a DEF dosing injector. A worn, restricted, leaking, or failed doser injector can affect regeneration performance, increase soot loading, and trigger aftertreatment-related fault codes. For ISX\/QSX 15L applications, correct OEM part number matching is important because aftertreatment configuration, engine control module calibration, and emissions hardware can vary by engine serial number and vehicle application. Verify fitment by VIN, ESN, original part number, and Cummins service information before ordering.\u003c\/p\u003e","brand":"Cummins","offers":[{"title":"Default Title","offer_id":47487703023837,"sku":"WP20002","price":579.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0735\/7808\/6621\/files\/WP20002.1.webp?v=1773979168","url":"https:\/\/wisentpartscenter.com\/products\/5300987-doser-injector-kit-for-cummins-isx-qsx-15l-new","provider":"Wisent Parts Center","version":"1.0","type":"link"}
