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

Such a pretty bottle and it feels so great on skin!
Size: 1.7 Fl Oz (Pack of 1), Size: 1.7 Fl Oz (Pack of 1)
I was so excited to try this serum, and honestly, it did not disappoint. What first caught my eye was the packaging—I’m a sucker for pretty bottles, and this one is stunning with its shimmery, rainbow-like colors. Even the serum itself has a subtle shimmer that matches the bottle, which I absolutely love. The scent was the first thing I noticed. It has a light floral smell with a hint of honey, almost like a soft version of the old Sweet Pea scent from Bath & Body Works. It’s not overpowering at all. You only really smell it when dispensing or applying it—once it’s on your skin, the scent completely disappears. No headaches, no lingering fragrance. Application-wise, this serum is silky smooth and spreads beautifully. It made me realize my skin wasn’t as soft as I thought—because after using this, my skin felt noticeably softer, hydrated, and plump. It absorbs well and leaves my skin feeling nourished without being greasy. It does contain retinol, so the warnings about avoiding the eye area and limiting sun exposure are important. I’ll definitely be pairing this with a good hydrating sunscreen, especially during daytime use. I plan to ease into it by using it once or twice a week until my skin fully adjusts. Overall, I love everything about this serum—the packaging, the light scent, the texture, and the results. My skin feels smooth, hydrated, and healthy. This is definitely a product I’m excited to keep using and would happily recommend.

Smells great and silky smooth
Size: 1 Fl Oz (Pack of 1)
⭐️⭐️⭐️⭐️⭐️ I’ve been using the Olay Super Serum for a few weeks now and I’m honestly impressed with how much it does in one step. My skin looks noticeably brighter and more even, and it feels super hydrated without being greasy or heavy. It absorbs quickly, which I love because I can layer moisturizer and makeup right after without any pilling. The texture is silky and lightweight, and a little goes a long way. I’ve also noticed my skin feels smoother and a bit firmer, especially around my cheeks. It gives a really nice healthy glow that looks natural, not shiny. If I had to mention one small thing, it’s that you need to use sunscreen during the day since it contains AHA — but that’s expected with brightening products anyway. Overall, this is a great all-in-one serum if you want brighter, smoother, more hydrated skin without using a bunch of separate products. I’d definitely repurchase and recommend it for anyone looking to simplify their skincare routine while still getting real results.

Miraculous and so inexpensive!
Size: 1.7 Fl Oz (Pack of 1)
This stuff is amazing! I am getting benefits I never dreamed…I have only had it 3 days but had to report my immediate results! I have a patch of seborrhea on my left eyelid that is an annoyance daily. I tried this serum on my eye and no burning or stinging. No irritation at all! I put my makeup on and thought little more of it. At the end of the day, no dry flaky patch or makeup issues there at all! No eye itching or irritation all day! This is something I thought I just had to live with. As for the general serum I think the lines around my eyes are less prominent and my skin feels soft and moisturized. And last I love the large bottle! Great value! And I am not embarrassed to have the bottle sitting on my sink… Overall I think it is liquid gold for a bargain price! Will definitely buy again. Truly unexpected miracle in a bottle! Highly recommend.
