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 300-624(satin) & 300-624BK(black) top-feed intake manifold kit provides two injectors per cylinder for hi-volume fuel demands, flexible fuel supply strategies, and dual-fuel capability. The top-feed, short runner, low-profile base intake manifold was conceived to package plenum mounted intercoolers for high-boost turbocharged or supercharged induction systems with a shorter overall height not possible with other existing intake manifolds. The plenum top is configured to be fitted with 105 mm throttle body part number 112-581 or similar models. The dual fuel injector 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. Available in satin and black finishes. Holley Lo-Ram intake manifold kits include all the sealing o-rings, plugs, and fasteners required for the installation of the kit.

Features:

  • Designed for GM LS Gen III and IV engines equipped with GM LS1/2/6 (cathedral port) cylinder heads
  • Provides best performance for forced induction (supercharged or turbocharged) engine applications with peak power at 7000-8000 rpm, depending on the application
  • Dual-injector, separate-passage, high-volume fuel rails with mounting hardware, dual-fuel capable, 8 AN o-ring ports
  • 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
  • Available with both as-cast satin and black power-coat finishes

Very lightweight but good everyday
Size: 500 Count (Pack of 1)
These are great for everyday use. I use them under bowls when I microwave, to collect pieces of food that I’m going to throw away while I’m cooking. Good enough for toast or a microwaved muffin. They are lightweight and not meant for heavy amounts of food.

Consistent quality
Size: 500 Count (Pack of 1)
This is the first time I’ve ordered this online and it is exactly what we have been using for years. We always use a plastic support and the plates themselves are flimsy. Good value. And easy to use. But I wouldn’t trust it to NOT leak.

Great non-toxic option for big families!
Size: 500 Count (Pack of 1)
I purchased these several times. We have a big family and paper plates are just part of our norm right now. I was looking for something that doesn't have forever chemicals lining the plates. These are perfect. You can't carry around the plate. These are for putting on the table and putting food on them :) But that's what we needed them for !
