Overview:

The Holley GM LS7 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 LS7 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.

Perfect Divider Wall!
Color: Iron, Color: Iron
This Divider Wall is perfect for creating a private and organized space! The sleek black design blends seamlessly into my room, and the build quality is excellent. It’s lightweight yet sturdy, standing firmly on the floor without wobbling. I use it to separate my desk area from my bed, and it makes the room feel more functional and professional. Highly recommended for anyone looking to divide their space efficiently while maintaining a modern aesthetic!

Great for separation and stands on its on without issues.
Color: Midnight
Nice panel! But ... if you plan to use as a bulletin board, not great. We are going to place styrofoam in between to see if can get things to stay in place. We homeschool and it keeps our grands from distracting each other.

Provides privacy without being stanoffish
Color: Steel, Color: Steel
Its a perfect way to get a lil bit of privacy, its the color steel. Its a little darker than the picture but it works. Free standing doesn't attach to furniture and takes maybe 10 mins to put together. It's about 5 feet tall. Very lightweight cover slides over the steel frame and zips st the bottom.

Perfect for my office space!!
It's a well packaged item including a simple tool set and a clear instruction. I put it together just by myself in about 15-20 minutes without any problems. The base is solid pieces of metal, and it stands very sturdy. It's also light enough for me to move it around in my office to serve different purposes. I like the color and the quality of the fabric. It blends in with my office space perfectly. I needed it as a partition between my desk and the door, and the background for my video conference call. Surprisingly, it can also deflect the air coming down from the AC vent behind my desk. I didn't expect it to 100% soundproofing (not its purpose), but I feel it did absorb some humming sound from my mini fridge behind my desk. I would recommend this to my colleague.
