These intake manifold and rail kits will work with OE (Original Equipment) or aftermarket cylinder heads. The 300-603(satin) \u0026amp; 300-603BK(black) front-feed, base-lower intake manifold provides two injectors per cylinder for hi-volume fuel demands, flexible fuel supply strategies, and dual-fuel capability. Offering this base intake manifold with fuels rails separately allows you to select your components individually as you build your induction system. Complete front-feed manifold kits are also available with dual fuel injectors, see P\/N's 300-625 \u0026amp; 300-625BK. The front-feed, short runner, low-profile base intake manifold was conceived to package with high-boost turbocharged or supercharged induction systems with a short overall height not possible with other existing intake manifolds. The Holley Lo-Ram complete intake manifold kits and throttle body adapters available as a machined casting 300-606 \u0026amp; 300-606BK are configured for a 105mm throttle body, see Holley P\/N 112-581 or similar models. 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.\u003cul\u003e\n\u003cli\u003eProvides Best Performance For Forced Induction\u003c\/li\u003e\n\u003cli\u003eDual-injector Separate-passage High-Volume Fuel Rails\u003c\/li\u003e\n\u003cli\u003eModular LS1 Lo-Ram Design Allows Customization\u003c\/li\u003e\n\u003cli\u003eAllows Installation In Most Applications Often Under Stock Hoods\u003c\/li\u003e\n\u003cli\u003eAvailable With Both As-Cast Satin And Black Power-Coat Finishes\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Holley EFI","offers":[{"title":"Default Title","offer_id":40289574944907,"sku":"HOL300-603","price":858.59,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0554\/5495\/7707\/files\/hol300-603-2e5829597a954ffcc965b8762ce170b2b9f674f9.jpg?v=1755621863","url":"https:\/\/jbspowercentre.com\/products\/gvmr-300-603","provider":"JBs Power Centre","version":"1.0","type":"link"}
