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 300-600 is the lower manifold in the 300-620 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 low height to aid the packaging of a plenum mounted air-to-water intercooler in a top-feed configuration. The short runner, low-profile base intake manifold intended for forced induction applications was conceived to package with an air to water plenum mounted intercooler with a shorter overall height than possible with other existing intake manifolds. 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.

Offers Complete Privacy
Color: Black, Size: 132in-Large Metal Base
We tried others that were nice but this particular room divider adds total privacy. We were looking for that. Easy to assemble. There is no gap if you position each petition close enough. The guality is very nice. Exactly what we were looking for.

Get help to mount on the wall!
sturdy, easy assembly, looks nice, but a bear to mount on wall by yourself. It is heavy and can be awkward to hold and drill holes as well. a template would have been nice and at the time i didn't think to make one. even then it can be tricky to find the hole you drilled in the wall. Also i recommend once mounted and if not in a stud to find a stud and drill a third hole with a longer screw to screw into a stud just to make sue it is sturdy. I mounted mine above the toilet in my bathroom and the crews are in sheet rock with plastic mounts. I drilled a hole though the cabinet brace and into a stud. Visions of it crashing onto my head while sitting there. LOL. a second person for install will longer the difficulty a lot.
