Holley LS Hi-Ram EFI Manifold - Black GM LS1/LS2/LS6

LS1/LS2/LS6 Cathedral Port EFI for 1 x 105MM Throttle Body

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.

*** The front and rear height measurements listed in the Specs section are referencing the overall height with the top plate installed. Please see the diagrams in the product images for other dimensions.

Very moisturizing with a great vanilla scent
I love this body oil. Very hydrating and smells amazing. It has replaced the original Palmer’s cocoa butter, body oil for me just because I like the smell better. It leaves my skin looking glowy and feels so smooth. I smell like vanilla all day. I like the pump top. It is easier to apply. Very silky consistency

Love the smell and great for my skin
This has become a permanent part of my shower routine. I use it right after I turn the water off while I am still wet, I cover my entire body from the neck down using about 8-10 pumps. I will wrap my body in a towel and finish getting ready (brush teeth, face moisturizer and blow drying hair) and then I will gently rub the towel everywhere incase there is any excess oil after it had the time to absorb into my skin. I dont think it leaves any greasiness at all, its really lightweight. What I love most of all is the smell though. A very nice, light, sweet vanilla smell lingers on your skin until your next shower. You have to put your nose pretty close to your skin to smell it so you wont be bothering anyone who had scent sensitivities. I have been using this for almost a year now and I still keep bringing my forearm to my nose to smell my skin because I love it so much. My skin has improved so much since I started using this.

JUST BUY IT!!! Finally found what I was looking for
This is the first time I have ever written a review - THATS how good this product is!! It smells like vanilla bean ice cream, it is so deliciously sweet and fragrant. I have been searching for something that leaves a strong yet natural scent on the skin and this is it. It makes me feel like a sweet and soft ethereal fairy princess and is so so so moisturizing on the skin. My bf loves it and has pointed out multiple times how soft my skin is just from a few uses I use it right out of the shower while my skin is still a bit wet. It is lightweight enough where it dries quickly enough for me to put my pajamas on without greasy-ness. I'm at work the morning after and can still lightly smell it on myself If you're looking for a sign - this is it - JUST BUY IT!!! :)

Light, Hydrating, and Non-Greasy — Perfect Everyday Body Oil
I purchased this body oil a little over a week ago, and overall, I have nothing but positive things to say about the product itself. The only complaint I have is with the packaging. When my order arrived, some of the oil had leaked in the box. The bottle doesn’t come with a separate cap—just a twist/lock feature that can easily come loose. Because of that, it must have unlocked during transit, causing a small amount of product loss. Luckily, it wasn’t bad enough for me to feel the need to return it. As for the oil itself—it’s lovely. The scent is light and pleasant, nothing overpowering. While I don’t pick up a strong vanilla note once it’s on my skin, it has a smooth texture that absorbs quickly without leaving any greasy residue. It’s very hydrating, and the bottle size feels generous for the price. If you’re looking for something heavily fragranced, this might not be the one for you, but it’s perfect as a layering oil or for anyone who wants a subtle, nourishing glow. Highly recommend!

Just Buy It
This smells AMAZING! The body butter smells amazing too but the oil smells so much like the Vanilla Amber Sand+Fog oil perfume. I’m so glad I have all three and went ahead and picked up some Vanilla body wash. My kids said I smelled like a bakery all day. I couldn’t stop sniffing my arm and clothes the scent sticks and such a wonderful combination to my perfumes that has vanilla notes. Also, makes your skin feel awesome after a shower. It’s not so greasy after application and gives your skin a beautiful glow in the light. BUY IT!
