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 lower overall height to fit under a stock or mildly modified hood in the front-feed configuration. The 300-621 Lo-Ram front-feed plenum entry was configured to provide a very low profile modular intake manifold suitable for turbocharged or centrifugally supercharged engines. 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 be coupled to the supercharger or turbocharger being used
  • Modular design allowing the use of front-feed plenum entry
  • Intake design facilitates custom inlet duct and throttle body placement
  • Low height to fit under a stock or mildly modified hood in the front-feed configuration
  • Front entry plenum flange allows design & fabrication of special throttle body adapters or inlet ducts for custom installations
  • Clears 4th Gen Camaro and C5 Corvette cowls and hoods without modification
  • High volume fuel rails and mounting hardware included with ¾”-16 o-ring ports (8 AN)

Amazing for evening skin tone
I’ve been using Palmer’s Skin Success Fade Milk and I’m very happy with the results. The lotion is lightweight, absorbs quickly, and doesn’t feel greasy at all. It keeps my skin well moisturized and over time I noticed my skin tone looking more even and brighter. I also like that it’s hydroquinone-free and contains niacinamide. The scent is mild and pleasant. Great quality product that delivers what it promises. I will definitely keep repurchasing!

Good for skin
Yes!!!! This actually works but the results are not permanent you have to continue using. But it does work for while in use. Would not recommend for the face though. Or should I say do not use often on face because it makes the face so oily. And not in a good way.

It works!
This is the only lotion I’ve been using on my body. I use koji acid Turmeric soap, and I use this lotion after. I’ve had these scars for years, and I’m definitely noticing a difference. I’m sure it’ll take months to finally get clear skin, but it does work. The lather could be better, so you do have to use a lot. I wish the bottle was bigger, especially since I use it on my entire body. So I have to use a lot. A bottle only last for about a month if your using it on large parts of your body. The smell isn’t bad at all, and it’s very lightweight. It doesn’t feel super moisturizing, but it’s good to SOLEY treat dark marks, but not your average everyday moisturizing lotion. But you can see a slight difference on my legs, and other parts have been clear very well. This is a great product, for a great price. I highly recommend pairing with a soap that treats dark spots.

Different package
I have been using this product for almost two years, and I absolutely love it, especially because I have very dry skin. It leaves my skin feeling extremely soft and well-moisturized even the next day. Over time, I also noticed that my dark spots started to fade. It is a great product, but it does take time to see results with dark spots. Yesterday, I ordered the same body lotion, but it arrived with a different packaging and formula. I was afraid it might affect the progress I’ve made with my skin, so I returned it and requested the original version I’ve been using.

Scent is off putting.
Seems to be a nice lotion but for me, the aroma is off putting. That makes it hard for me to use on a consistent basis. It is moisturizing and not greasy. It absorbs well into my skin. I wish it were fragrance free. My spots are still with me but that’s my fault.
