{"product_id":"holley-efi-300-603-holley-efi-lo-ram-intake-manifold","title":"Holley EFI 300-603 Holley EFI Lo-Ram Intake Manifold","description":"The Holley LS1\/2\/6 Lo-Ram intake manifold kits are designed for GM LS Gen III and IV engines equipped with GM LS1\/2\/6 (cathedral port) cylinder heads. 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.\u003cbr\u003e\u003cbr\u003e\u003ch5\u003eSpecifications:\u003c\/h5\u003e\u003cbr\u003e\u003ctable class=\"descr-table\" border=\"0\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eCylinder Head Type\u003c\/td\u003e\n\u003ctd\u003eLS1\/LS2\/LS6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_ASC\u003c\/td\u003e\n\u003ctd\u003eHolley Performance Emission Code 3: This part is legal for sale and use on Uncontrolled (Non-Emissions Controlled) Vehicles and Racing Use Only Vehicles.
