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 manifolds will work with OE or aftermarket cylinder heads. 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 300-620 top-feed plenum entry configuration is designed to allow the included Hi-Ram 105 mm plenum top to be fitted to a low-profile base intake manifold. 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.

Features:

  • Designed for GM LS Gen III and IV engines equipped with GM LS1/2/6 (cathedral port) cylinder heads
  • Designed for forced induction (supercharged or turbocharged) engine applications with peak power at 7000-8000 rpm depending on the application. With forced-induction and the short runner length the engine rpm at which peak power occurs is more likely to
  • Modular design allowing the use of the included top-feed plenum entry
  • 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
  • High volume fuel rails and mounting hardware included with ¾”-16 o-ring ports (8 AN)

PERFECT SOLUTION FOR SMALL SPACES.
I recently purchased the Tutotak 6-Tier Book Shelf for my son's room, and I couldn't be happier with it! The 6-tier design is a huge plus. It allows for plenty of storage without taking up too much floor space. The shelves are just the right height for storing books, toys, and decorative items. The vertical design maximizes the use of space, making it ideal for a smaller room like my son's. Sturdiness: I was pleasantly surprised by how sturdy this shelf is. Despite its slim profile, it holds up well even with a decent amount of weight on each shelf. Assembly: It was easy to assemble, and all the parts were clearly labeled. I was able to set it up within about 30 minutes by myself, and everything lined up perfectly. The instructions were straightforward, so I didn't have to spend much time figuring it out. Functionality: Not only is it great for books, but the different levels are also perfect for organizing his toys, art supplies, and even some of his favorite collectibles.. Final Thoughts: I’m really impressed with this shelf. It’s well-built, space-efficient, and versatile. It has made a huge difference in organizing my son’s room without making it feel cramped. If you have limited space and need something practical but stylish, I highly recommend this bookshelf!

Super cute
The shelf is cute, and super easy to set-up. Be careful with the screws, I stripped the magnet screw/hole a little bit. Street that I was a little weary on over-tightening the four corners of each shelf. Make sure you use the wall straps bc it will be a little wobbly.

Very impressed with this! It was very easy for me to put together without any help. Very sturdy pieces and seems well made. Really can’t beat the quality for the price! The glass door on the bottom really dresses up this shelf. I will probably buy more of these for other rooms in my house.

Elegant shelf, easy assembly!

I almost returned this because I didn’t think I could put it together, but the step by step picture instructions were easy to follow, and I assembled this in about 50 minutes, taking my time and also wiping down each wood piece so it would be ready to go once finished. This came packed very well and no parts were missing or messed up. It’s very elegant looking for being inexpensive and just what I needed budget wise and style wise. It is sturdy and beautiful and I like it very much and am glad I kept it, it is worth it!
