Holley EFI LS Hi-Ram Intake Manifold Bases
Holley EFI LS Hi-Ram intake manifold bases are cost-effective alternatives to fabricated sheet metal for high performance applications where induction system height is not limited. Coupling these cast aluminum Hi-Rams with the high flowing LS-style cylinder heads has outstanding potential for N/A and forced induction applications at a budget-minded cost. These modular lower manifolds accept a wide range of carbureted and EFI tops, making them attractive to builders and fabricators as the perfect foundations for custom induction systems. Fuel rails are included and machined for -8 AN O-ring fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system. The aggressive, bold, race-bred styling of Holley GM LS modular Hi-Ram lower manifolds will make bad intentions clear for drag race, muscle car, marine, off-road, sand rails, pulling trucks, track, and street-rod applications.

Keeps me cooler than before!!
Color: Light Gray, Size: Full / Queen (90"x90")
I have been going back and forth about buying the Rest comforter but it is so expensive and then I stumbled across this. I am very pleased, it is light and one side usually stays cool to the touch. It does warm up with body heat but usually I let it sit in front of the fan for few minutes and it’s cold again. It was made a huge difference and it good quality for what you pay.

Silky comfort
Color: Light Gray, Size: Full / Queen (90"x90")
I love this comforter. I’ve been using a blanket I ordered on another site for the last year that I loved but needed a new one because my son got bubble gum on it. I ordered this one after searching for a a couple of days. I was initially disappointed because it didn’t feel like it had the same cooling factor as my prior blanket. However, after sleeping with this blanket for the past 2 nights, I can say I’m in love. It’s still “cool”, just in a different way. I’m so excited to go lay down. Lol. It feels like a silk sandwich with light, soft comforter material on the inside. Silky and cool. Definitely recommend.

Excellent purchase
I love everything about it. The color, the soft cool texture and it drapes nicely over the sides of my mattress. It’s very beautiful. Perfect for the warmer season. I washed and dried it when I received it and it came out well. I love sleeping with it and so do my cats. A very excellent buy for little money
