{"product_id":"plenum-top-for-ultra-lo-ram-300-621","title":"Plenum top for Ultra Lo-Ram 300-621","description":"The Lo-Ram intake manifolds are designed for forced induction (supercharged or turbocharged) engine applications and the 105 mm throttle body part number 112-581 or similar models. The base intake manifold is designed with a lower overall height to fit under a stock or mildly modified hood. The 300-621 Lo-Ram 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":47925477998837,"sku":"GVMR_300-604","price":206.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0751\/7025\/0997\/files\/300-604_01.jpg?v=1775437349","url":"https:\/\/berserkerms.com\/products\/plenum-top-for-ultra-lo-ram-300-621","provider":"Berserker Motorsports LLC","version":"1.0","type":"link"}
