LS3 HI-RAM IM, EFI, 1 X 105MM LS-BLACK
The Holley GM LS3/L92 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 LS3/L92 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.

So Pretty
Color: B
A beautiful necklace for my beautiful daughter. She is 12 years old and starting to appreciate pretty jewelry rather than fun/colorful/kid’s jewelry; BUT - she’s 12!!! No real gold or fancy jewelry just yet! Gifts like this perfectly hit the mark right now. It looks beautiful, feels fun and trendy but more mature, has held up well to the wear and tear of a 12 year old, and is the perfect size for her at this time. She loves anything with her initial on it so she, of course, adores this necklace. She wears it several times a week. She has occasionally worn this necklace to bed on accident and it has not broken or gotten damaged in any way. All in all, I recommend this cute necklace as a beautiful gift!

Classy and Pretty Necklace Set
Color: C, Color: C
This is a very pretty necklace set. The chains are thin, delicate, and lightweight in a yellow gold color. I feel they are the same as what is pictured. I especially like the lettering of the small font, which makes it look classier than others I’ve seen of the same style. So far, they seem to be pretty durable to wear as they don’t feel like they’ll immediately break if they were to get snagged on a top. I have a smaller neck as I’m small myself (about 100lbs), and the chains fit me perfectly on the tightest clasps. They are adjustable. Some metals, such as nickel, cause me to have a slight skin reaction, but this did not. It included a small pink jewelry wipe, much like that of one for eyeglasses, which I’ve never seen before. It also had a sweet little blank note card in a tiny printed envelope inside the jewelry box to make it extra special should it be given as a gift. These were thoughtful details that gave it that little extra something for me.
There were only two things I wish were a little different. The first is that they are two separate necklaces, and I’d like if they were connected as one, so you’d only have to clasp them on once. The second is that rather than the little wipe, I’d of personally preferred a little dust bag to store them, as many jewelry pieces include. However, I don’t think either of these takes away from their overall style or quality, so it did not make me deduct a star.
Overall, I feel this is a lovely set to purchase for yourself, or to give as a gift to someone special. I definitely feel the value for your money is there for these necklaces.

Beautiful, Dainty Layered Set!
Color: S, Color: S
I am so impressed with this little necklace set! I was looking for something simple and elegant for daily wear, and this initial necklace set exceeded my expectations for the price.
What I Loved:
1. The Packaging: It comes in a very cute, gift-ready box with a "Handmade with Love" message and a floral insert. It even includes a "Thank You" sticker, which is a really sweet touch if you're planning to give this as a gift.
2. The Design: You get two separate necklaces. One is a classic, sparkly water-wave chain, and the other is a dainty satellite chain (the one with the little beads) featuring a small, polished initial "S."
3. Versatility: Since they are two separate pieces, you can wear them together for that trendy layered look or just wear one at a time for something more subtle.
4. Quality: The gold tone is bright and has a high-end shine to it. The clasps feel secure, and they both have adjustable extenders so you can get the layering lengths just right.
What I am concerned about:
Polish: I liked the finish and quality but I am skeptical about the tarnishing on the necklace. This might loose with time. I guess the time will tell.
The Verdict:
If you’re looking for a thoughtful, personalized gift or just a cute new addition to your jewelry box that won't break the bank, this is it. It looks much more expensive than it actually is!
