[More Info]
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 or aftermarket cylinder heads. The 300-604 is the plenum top in the 300-621 complete kit. Offering this separately allows you to select your components individually as you build your system. 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 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.
Features:
  • For Forced Induction Engines With Peak Power At 7000-8000 Rpm
  • Modular Design Allowing The Use Of Front-Feed Plenum Entry
  • Custom Inlet Duct And Throttle Body Placement
  • Fit Under A Stock Or Mildly Modified Hood In The Front-Feed
  • Clears 4Th Gen Camaro/C5 Corvette Cowls/Hoods w/o Modification
  • High Volume Fuel Rails And Mounting Hardware Included
