Supplied as a replacement direct fuel injector for the GM L87 6.2L EcoTec3 V8 and the closely related Gen V 6.2L applications noted below. This listing covers the component described here only; hardware such as bolts, seals and gaskets is included only where the specification list says so.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFunction\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA direct fuel injector meters fuel into the combustion chamber at high pressure, so its spray pattern and flow rate set both emissions and driveability. A clogged or leaking injector typically produces a single-cylinder misfire, a strong fuel smell at idle, black smoke, elevated fuel trims on one bank, or a cold-start stumble that clears as the engine warms.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications as documented\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eComponent\u003c\/strong\u003e: Direct fuel injector\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM part number\u003c\/strong\u003e: 12668390\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross-reference\u003c\/strong\u003e: FJ121 series reference appears in the truncated title\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine\u003c\/strong\u003e: 5.3L stated in title; 6.2L Gen V flagged in listing match\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel years\u003c\/strong\u003e: 2014-2018 (supplier stated)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage contents\u003c\/strong\u003e: 1 x injector per piece (seals not confirmed as included)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eEngine: 5.3L stated in title; 6.2L Gen V flagged in listing match.

GM built the 6.2L V8 in several forms, and L86, LT1, LT2 and LT4 components are not automatically interchangeable with L87 parts. Before ordering, confirm the engine RPO code and the original part number against the vehicle, and treat this listing as a guide rather than a substitute for that check. Specialist engine repairs should be carried out by a qualified technician.\u003c\/p\u003e","brand":"Global Engine Components","offers":[{"title":"Default Title","offer_id":54770011078974,"sku":"L87-INJ-12668390","price":126.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0948\/1486\/3678\/files\/H624b0369c661480baf423c41e4ddfec9G.jpg_640x640_b4883e55-6d6b-4b7a-aba1-486c1267bcdd.jpg?v=1793097435","url":"https:\/\/asiapartsstore.com\/products\/gm-6-2l-v8-ecotec3-direct-fuel-injector-12668390-silverado-sierra-1500","provider":"Asia Parts Store","version":"1.0","type":"link"}
