Supplied as a replacement intake manifold 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\u003eThe intake manifold distributes charge air evenly across the cylinders and provides the mounting pads for the throttle body and the direct-injection hardware. A sound manifold matters more on a direct-injection engine than on an older port engine, because any leak downstream of the throttle body is unmetered air that the engine control module cannot account for. Typical symptoms of a failed manifold or manifold gasket are a rough or hunting idle, lean fuel trims, a whistle under light throttle and a check-engine light.\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: Intake manifold\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM part number\u003c\/strong\u003e: 12639087; 12724936\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine\u003c\/strong\u003e: 6.2L Gen V V8 - L86 named in title, L87 flagged in listing match\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel years\u003c\/strong\u003e: 2014-2026 (supplier stated)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage contents\u003c\/strong\u003e: 1 x intake manifold (gaskets and hardware not confirmed as included)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eEngine: 6.2L Gen V V8 - L86 named in title, L87 flagged in listing match.

Any disturbed injector should be reseated with a new combustion seal.

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":54770008654142,"sku":"L87-IM-12639087","price":626.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0948\/1486\/3678\/files\/H2fe95e7a686b4150a743add408d5d5fd5.png_640x640_b6de738d-2529-4643-b25b-211313af8723.png?v=1793097408","url":"https:\/\/asiapartsstore.com\/products\/gm-l87-6-2l-v8-intake-manifold-12639087-12724936-silverado-1500-sierra-1500-2014-2026","provider":"Asia Parts Store","version":"1.0","type":"link"}
