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

Not a big fan
Oily and doesn’t absorb well. The scent was very overpowered with honey.

Amazing product
I have just purchased my 7th jar! I absolutely love this product...and its American made! It leaves my skin soft, radiant and glowing! I didn't tell anyone about using it and people started asking me what I was doing differently. I get complements about my youthful glow! This company makes an amazing product and I hope that it will always be available! I have friends and family members hooked on it now. My mom just dropped a stocking stuffer hint to me tonight for another jar!

Legit balm. Not whipped. Made in USA.
Legit tallow balm. Not whipped. I love this stuff. It's the only thing that soothes, softens, and relieves my dry skin in the winter. Also made in USA, which is a priority for me.

Great winter moisturizer! Not greasy & absorbs well!
I needed a moisturizer that would last in colder weather. My skin is oily/normal and works well with my other facial products. I strictly use The Ordinary products and add this at the end to seal in the moisture. Pretty surprised how quickly this absorbed in to my skin. Has no scent and melts quickly on finger tips. I use it on my face and heels of my feet. Honestly love this addition to my fall/winter skincare routine. A little goes a long way! I have been using for a month now with great results. Definitely a great buy!

Great product if you can actually use it
Of the 4 orders I've placed for this lotion, only 2 have come perfectly. One of them came leaking tallow out of the container and package, and then it's replacement arrived with the jar completely shattered. The tallow itself is so hydrating and smells great, but if the company itself needs to fix it's packaging.
