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)

Beautiful and well made
Color: Rectangular Tissue Box-retro
Such a beautiful and well made kleenex box. I absolutely love mine. I ordered 2 more after receiving my 1st one for my office. Easy to get the box in. Looks so nice and the kleenex feeds out of it easily. I even ordered my parents one for their office as a gift.

Very Pretty and Nice Addition to my Living Room
Color: Square Tissue Box-retro
These look nice and were reasonably priced. Putting my tissue boxes in these holders also stopped my dog from tearing up boxes of tissues (he likes to tear up paper). he has not bothers these. They help the tissues blend into the decor without the distractions of the funky colors on the cardboard boxes.

Like it so much. I've got a second one
Color: Square Tissue Box-retro
Liked it so much. I've got a second one. This tissue box cover is so elegant and beautiful that I bought another one. The bottom snaps in place very nice and the threading around the box is beautifully done. The brown color goes very well with all of our oil rub bronze pictures in the house. It is very elegant and I just love it.
