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 300-600BK is the lower manifold in the 300-620BK complete kit. Offering this separately allows you to select your components individually as you build your system. 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 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.

XeGe Luxury Faux Fur Throw Blanket
I like this throw I do wish it was a little wider. It's very soft but does shed.

So Soft!
Size: 50" X 60", Color: Cheetah Print Brown
This is the softest coziest blanket! It's a good medium weight, and does not shed. It's the one I grab every time I need a blanket.

Best blanket EVER!
I honestly LOVE this blanket! I never thought I would be so in love with a blanket, but here I am! I’m planning on buying more to safe as replacements for this one is old. When I first got it, I was skeptical I would like it or not. It was so much thinner than I expected and the shape was an odd shape (long and narrow, not a square shape like I’m used to my blankets being). To me it resembled a rug more than a blanket. But, from the first night of using it I was OBSESSED! It keeps me warm and is SO comfortable! I use it on either side, and it keeps me warm either way. If you are debating purchasing this blanket! DO IT! You won’t regret it! Even my cats love it!

Functional Stuffed Animal Storage
Size: L For Adult, Color: Ombre Purple (Cover Only)
This bean bag cover solved our stuffed animal takeover! It’s super soft and fluffy too! The adult size one is really large and cozy! -make sure you have enough to fill it with! It can fit stuffed animals, extra pillows, and blankets too! We love the purple color! It’s been dragged here and there and is holding up well.
