The base intake manifold is designed with a lower overall height to fit under a stock or mildly modified hood in the front-feed configuration. The 300-621 Lo-Ram front-feed plenum entry was configured to provide a very low profile modular intake manifold suitable for turbocharged or centrifugally supercharged engines. The fuel rail kits come with two sets of brackets. A set for long (usually standard length) fuel injectors and a set for short (such as Pico, or LS7) fuel injectors.","brand":"Holley EFI","offers":[{"title":"Default Title","offer_id":47925599600885,"sku":"GVMR_300-602","price":554.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0751\/7025\/0997\/files\/300-621.jpg?v=1775442741","url":"https:\/\/berserkerms.com\/products\/base-manifold-and-rail-kit-for-ultra-lo-ram-300-621-gm-ls1-ls2-ls6","provider":"Berserker Motorsports LLC","version":"1.0","type":"link"}
