Description

Black Finish

Part Number: 300-624BK

The 300-624(satin) & 300-624BK(black) intake manifold kit provides two injectors per cylinder for hi-volume fuel demands, flexible fuel supply strategies, and dual-fuel capability. The short runner, low-profile base intake manifold was conceived to package plenum-mounted intercoolers for high-boost turbocharged or supercharged induction systems with a shorter overall height not possible with other existing intake manifolds. The plenum top is configured to be fitted with 105 mm throttle body part number 112-581 or similar models. The dual fuel injector 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. 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. Holley Lo-Ram intake manifold kits include all the sealing o-rings, plugs, and fasteners required for the installation of the kit. Available in satin and black finishes.

Features and Benefits

• Dual-injector, separate-passage, high-volume fuel rails with mounting hardware, dual-fuel capable, 8 AN o-ring ports
• Low height to aid the packaging of a plenum mounted air-to-water intercooler in a top-feed configuration or to fit under a stock or mildly modified hood in the front-feed configuration
• Provides best performance for forced induction (supercharged or turbocharged) engine applications with peak power at 7000-8000 rpm, depending on the application
• Designed for GM LS Gen III and IV engines equipped with GM LS1/2/6 (cathedral port) cylinder heads
• Available with both as-cast satin and black power-coat finishes
