{"product_id":"ls6-intake-manifold-3","title":"LS6 Intake Manifold","description":"The GM Performance Parts 12573572 intake manifold, also known by its casting numbers 12573572 and 12561184, is a component designed for GM's LS engine family. This LS6-style manifold is engineered to enhance performance for 4.8L, 5.3L, 5.7L, and 6.0L displacements.\n\nThis intake manifold is stated to be compatible with a range of LS engines, including applications from 1997 to 2007. It is often paired with cathedral port heads and can be used with drive-by-cable throttle bodies. The manifold typically comes complete with a fuel rail and a pre-installed MAP sensor, simplifying installation. Users have noted that the LS6 intake can provide noticeable gains, especially above 5,000 RPM, with some sources citing an additional 5 HP and 15 lb-ft of torque over earlier LS1 intakes.\n\nWhile the manifold is generally compatible with various LS applications, some modifications may be necessary for earlier models. For instance, fitting a 1998 LS1 may require updating coolant tubes or modifying the intake's ribs. Users should compare the part number and verify the casting numbers against their original components to ensure proper fitment. The product is described as a used OEM part, and may exhibit minor scratches or markings consistent with normal use.","brand":"LS6","offers":[{"title":"Default Title","offer_id":52688585130296,"sku":"12573572","price":74.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687902137.jpg?v=1784891430","url":"https:\/\/store.motormia.co\/products\/ls6-intake-manifold-3","provider":"MOTORMIA","version":"1.0","type":"link"}
