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)

Soft pillow
Color: Soft, Size: Standard(24"×16"×5.5")
This latex pillow has been a great addition to my sleep routine. It offers the perfect balance of softness and support, especially side sleeping. I noticed less pressure on my neck and shoulders after using it. I also like that it’s made with natural latex and free from harsh memory foam chemicals. The removable cover is convenient, and the packaging makes it feel like a premium product.

Perfect Balance of Comfort & Support!
Color: Soft, Size: Standard(24"×16"×5.5")
I absolutely love this pillow! The Talalay latex feels incredibly supportive while still being soft and comfortable. Unlike memory foam, it doesn't trap heat or give off any chemical smell-just clean, natural comfort. I've noticed a huge difference in my sleep quality; it relieves pressure from my neck and shoulders, and I wake up without stiffness. The Tencel cover is smooth, breathable, and removable for easy washing, which makes it feel extra fresh. The packaging was beautiful, making it feel like a premium gift right out of the box. If you're looking for a high-quality natural pillow that's supportive, durable, and chemical-free, this is it. Highly recommend!

Hard to judge thickness with only dimensions to go by
Color: Soft, Size: Standard(24"×16"×5.5")
Very nice quality, just what I hoped for. But it's just too thick for me. I'm thinking of using my electric knife to try to skim enough off to be usable. I've slept most of my life on latex pillows and have not enjoyed using other pillows.

Good pillow, but too high for my neck
Color: Soft, Size: Standard(24"×16"×5.5")
I love the Talalay latex for the quality, and that there is no smell. However, it is too high for my neck. I wish the company would make it in a 3" version, instead of just 5.5". They do have a "slim" version, but it is not even the same kind of pillow. It measures 2.5" and the back side is completely flat, so you can not turn it in over for use. The company basically took this 5.5" version and cut it in half for the slim.

The Ultimate Natural Latex Pillow
Color: Soft, Size: Standard(24"×16"×5.5")
I recently switched to the Talatex 100% Natural Premium Latex Pillow and it has transformed my sleep. Unlike synthetic memory foam, this Purefusion Talalay Latex is incredibly supportive yet soft, providing excellent pressure relief for both my neck and shoulders. I appreciate knowing there are no harsh chemicals in the core.  It retains its shape perfectly night after night and stays cool thanks to the breathable material. The quality is immediately apparent, especially with the removable Tencel cover, which is luxuriously smooth. It arrived in a beautiful package, truly making it the best gift for anyone seeking a healthier, more comfortable night's sleep. Highly recommended!
