Overview:

The Holley GM LS1/LS2/LS6 Modular Hi-Ram Intake Manifold is introduced as a cost effective alternative to fabricated sheet-metal for high-performance applications where induction system height is not limited. Coupling this Hi-Ram intake with the high flowing LS1/LS2/LS6 style cylinder heads has outstanding potential for N/A and forced induction applications at a budget-minded cost. Aggressive, bold, race-bred styling will make bad intentions clear for drag race, muscle car, marine, off-road, sandrails, pulling trucks, track, street-rod applications and more!  The base is designed to be modular in configuration to accept a wide range of carbureted and EFI tops and to be attractive to builders and fabricators as the foundation for custom induction systems.  Runner length and the tapered cross-section designed to perform well for a wide range of engine configurations  EFI fuel rails are machined for -8AN O-ring Fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system and come standard with EFI Hi-Ram kits.  Cast aluminum construction.  Intended for use on N/A or forced induction engines in the 6.0 to 7.0+ liter range, max power at 7000-8000+RPM.

Did not fade my dark spots.
This is an amazing moisturizer. I love how light and creamy it is. It goes on and absorbs well with a light fragrance. Only 4 stars because it did nothing at all for dark spots. While really sad about that I would buy again as I like it that much.

A bit thinner than expected
This body cream feels nice on the skin and absorbs quickly without feeling greasy. It is a little thinner than I expected for a cream, but it still leaves my skin feeling soft and moisturized. The scent is light and pleasant too.

Lightweight daily moisturizer for the softest skin (bonus: incredible subtle scent)
Already repurchased, will absolutely continue to be a staple in my routine. Smells amazing, lightweight texture that easily absorbs into my skin, and leaves my skin feeling so soft even a full 24+ hours later. Incredible price for the amount and quality of product. Dove you did your big one with this one.

Just an OKAY Moisturizer, That's it.
I think this is a good moisturizer, as far as anything else it claims such as an even skin tone, I wouldn’t agree. I used the bottle and didn’t notice any changes in my skin and blemish appearance. It’s not too thick and it’s not greasy. I will say I had a successful run with brightening my inner thighs. I added this to the mix, and for some reason, I began chafing leaving Little bumps in my inner thighs that turned into 50-60 dark spots 😭 I’ve never had a problem with chafing or dark spots from bumps in my inner thighs before. I’m not sure if it because I was using it in conjunction with something else it caused issues. I would recommend it as a lotion, but that’s it.

Must Have Beauty Product
This one of my favorite and must have beauty products. Works so quickly for chapped lips and just keeping my lips soft every day. The formula isn’t sticky at all and you can really feel how hydrating and nourishing it is
