Overview:

The Holley GM LS1/LS2/LS6 Modular Hi-Ram Intake Manifold is introduced as a cost effective alternative to fabricated sheet-metal for high-performance applications where induction system height is not limited. Coupling this Hi-Ram intake with the high flowing LS1/LS2/LS6 style cylinder heads has outstanding potential for N/A and forced induction applications at a budget-minded cost. Aggressive, bold, race-bred styling will make bad intentions clear for drag race, muscle car, marine, off-road, sandrails, pulling trucks, track, street-rod applications and more!  The base is designed to be modular in configuration to accept a wide range of carbureted and EFI tops and to be attractive to builders and fabricators as the foundation for custom induction systems.  Runner length and the tapered cross-section designed to perform well for a wide range of engine configurations  EFI fuel rails are machined for -8AN O-ring Fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system and come standard with EFI Hi-Ram kits.  Cast aluminum construction.  Intended for use on N/A or forced induction engines in the 6.0 to 7.0+ liter range, max power at 7000-8000+RPM.

Size: 6 Panels, Color: Black
The VEVOR Room Divider is good, it gives the privacy that I want and was easy to assemble.

Super Value
Size: 4 Panels, Color: Grey, Size: 4 Panels, Color: Grey
While not elegant, these dividers are study, stable, and made of surprisingly high-quality materials for the price. The fabric has a heavy-duty feel and stretches nice and tight with no need to individually Velcro the top and bottom in place as compared to other options. That makes screwing-in one bolt per panel section a bit of a challenge that is best done with two people. However, the results are worth the effort. Otherwise, super quick and simple assembly. The included hex wrench works OK. However, using a 5/32nd inch (4 mm) hex bit in a manual or electric screwdriver dramatically speeds assembly and disassembly. Everything fits nice and neatly back into the divider's shipping box provided one carefully preserves its packing materials and notes how the box was originally packed. Our organization ordered 8 additional 4 panel sets after initial testing of one set of panels indicated that they were an extremely cost-effective alternative to renting "pipe and drape" to support displaying and dividing artwork. We plan to use rubber backed pushpins (also available via Amazon) to affix items to the dividers as needed.

Great Value
Size: 4 Panels, Color: Grey, Size: 4 Panels, Color: Grey
These are great value and ideal for a divider that needs to be moved or maneuvered a small distance on a regular basis. Assembly is quick with a drill (don't over-tighten). Fabric seems of good quality and the unit seems sturdy expecially when linked together.

Great value, perfect for our infant room!
Color: Black, Size: Standard - 4 Panel
Great product, sturdy design and easy to build! It is a fairly light weight item, which aids in the maneuverability of the divider. The color was as described and is dark enough to block the light from our sleeping infants! I do love that you are able to see through the slats and see the child sleeping- if you are looking for something with MORE privacy, this is not it. It has great coverage area and is dark and a wonderful value for the price, however, you are able to see through the areas where each panel connects!
