Overview:

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 300-624(satin) & 300-624BK(black) top-feed intake manifold kit provides two injectors per cylinder for hi-volume fuel demands, flexible fuel supply strategies, and dual-fuel capability. The top-feed, 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. Available in satin and black finishes. Holley Lo-Ram intake manifold kits include all the sealing o-rings, plugs, and fasteners required for the installation of the kit.

Features:

  • Designed for GM LS Gen III and IV engines equipped with GM LS1/2/6 (cathedral port) cylinder heads
  • Provides best performance for forced induction (supercharged or turbocharged) engine applications with peak power at 7000-8000 rpm, depending on the application
  • 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
  • Available with both as-cast satin and black power-coat finishes

Does the job. Made a set of battery cables that look professionally manufactured using a hydraulic crimper. The heat shrink adds a nice touch.

These things are BRIGHT!
Color: 4.5" Combo Light
After watching some videos, I decided to pick up these lights to go on my work truck. I work in a lot of remote locations across CO, WY, and NM. Traveling at night down dark highways and dirt roads can be a little stressful when wildlife is out. Not anymore with these lights! I can easily see anything in the ditches around me and at least 3/4 of a mile ahead of me. I’ve been running them for a few months and have had zero issues out of them. They seem to be super durable, easy to install with all the wiring included, look great on the truck, and you cannot beat the price to performance value. It’s also nice that the include yellow lenses to change the color of the beams for fog. Don’t waste your money on more expensive lights, these will get the job done perfectly for a lot less.
