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

Happy it is unflavored
Flavor Name: Unflavored, Size: 1.46 Pound (Pack of 1)
I was worried about the taste based on some of the reviews. I tried it in my coffee, and I'm glad I did it that way. I keep coffee in the fridge, so that is what I mixed with one tablespoon of this. I use half and half and no sugar. I tasted it. It tastes like burnt coffee. Not a bad thing...thats just what the taste it added. I decided to see what would happen if I added a splash of a flavored creamer. The taste went away instantly. Hope this helps someone!

Fantastic product, dont like the texture - mix with food. Still 10/10 💩🎉
Flavor Name: Orange, Size: 15 Ounce (Pack of 1)
Taste: While the product doesn’t taste bad, preparing it as directed results in a very mild orange flavor. -as a drink I would prefer more flavor. Texture: The psyllium husk absorbs water extremely quickly—even in cold or room-temp water—which is just the nature of the ingredient itself. Because it starts to gel so fast, you have to chug it, and even then it can be difficult to get down. (I personally gag at it, but I have sensory issues) If the gel like texture is an issue for you, I found it more palatable mixed into food with water on the side. Texture aside, the product itself is highly effective. Mixability: It doesn’t always mix smoothly and tends to clump. Again nature of the ingredient not the brand. The powder is very fine and non-gritty perfect for other mixings. Side effects: I had uncomfortable bloating the first time (2 scoops/ full glass), I recommend starting with (1 scoop or less/full glass) Dont rush it. Increase it from there as you grow tolerance. You may feel very full. - it helped me eat less!

Works great and easy to stick with daily
Flavor Name: Orange, Size: 15 Ounce (Pack of 1), Flavor Name: Orange, Size: 15 Ounce (Pack of 1)
I started taking Metamucil to improve my digestion, and it’s been a great addition to my daily routine. After using it consistently, I’ve noticed everything feels more regular and just overall better. One thing I really like is how easy it is to take. It mixes well and goes down pretty smooth, especially if you drink it right away. It’s not nearly as bad as I expected taste-wise. I also feel like it helps me stay a little fuller throughout the day, which has been a nice bonus. No stomach issues or discomfort for me, and it’s been very consistent in how it works. Overall, I’m really happy with the results and plan to keep using it long term.
