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

Nontoxic sunscreen
Size: 1.7 Fl Oz (Pack of 2)
Excellent sunscreen! Nontoxic and gentle. I have sensitive skin and chemical sunscreens can irritate my skin, so I switched to this one. It has a creamy feel, but doesn’t make your skin look or feel oily. I have dry-normal skin, for reference. It initially has a bit of a white cast, but once rubbed in you don’t notice it.

Good sunscreen, but the shade didn’t work for me
Color: Medium
I bought the Colorescience Flex in Medium because I had seen great reviews and liked the idea of a tinted mineral sunscreen. The formula itself felt really high quality and it did provide good sun protection, but the shade didn’t end up working for my skin tone. ✔️ What I liked: - Great daily mineral sun protection. - Lightweight texture and easy to apply. - Didn’t irritate my skin or cause breakouts. - Nice natural finish at first. ❌ What I didn’t like: - On my skin, the Medium shade looked orange. - The color didn’t blend well with my undertone. - I had to work it in quite a bit to avoid a noticeable line with my neck. I think the formula is really good, but the shade selection definitely requires care. In my case, it just wasn’t the right match

Finally found my perfect match!! In foundation!
Color: Medium, Color: Medium
I’ve used many high-end foundations over the years, but Colorescience has become my everyday favorite. It feels incredibly lightweight on the skin and provides a natural, healthy-looking finish that doesn’t feel heavy or cakey. The added SPF is a huge bonus and makes my morning routine so much easier. I also love how perfectly it matches my skin tone, it blends seamlessly and looks like my skin, just more even and polished. If you prefer a natural, lightweight foundation with the added benefit of sun protection, this one is definitely worth trying.
