The #1 EFI conversion system just got better! Introducing Sniper 2 EFI - a self-tuning, easy-to-install, EFI conversion for common 4-barrel (4150 flange) style carburetors.

Like all Sniper EFI systems, Sniper 2 is designed to work with the Sniper Ecosystem that includes Hyperspark ignition, complete fuel systems, multiple user interfaces/dash displays, and more.
New for Sniper 2 is the optional Power Distribution Module (PDM). This cost-effective and optional accessory isolates the core of your EFI and ignition wiring into one, easy-to-use location. Simply slide the stripped wire ends under the positive lock connector and tighten down the set screw. Battery and a switched 12-volt source is all that's required from your vehicle to power the PDM and your Sniper EFI.
Make your classic drive like a modern fuel-injected vehicle, including easy cold starts, smooth drivability, and improved fuel economy! Sniper 2 is designed to be installed at home in your garage with limited tools and the support of Holley's comprehensive installation manual and videos. The user-friendly setup wizard allows you to answer a few simple questions about your engine and the system will begin self-tuning with no laptop or tuning experience required.

Perfect earring tree
Color: Bronze
I was so tired of fumbling through a handful of tangled earrings in my jewelery box every morning - went looking for something to organize them and found this lovely tree. Since I am a admirer of all things bird, the design appealed to me. I was a bit worried it might be too garish, but was pleasantly surprised. The burnished copper-like finish is quite nice, and the embossed designs on the trunk and leaves give it a three-dimensional look. The nest is sturdy and holds my rings and bracelets, and I could hang necklaces from the branches (but I have another place for those.) I was worried it would be too large for my counter top - it is 17" tall x 15" wide - but it works well as a decorative piece. The sturdy base (7"x3") provides stability. Lots of holes for earrings and works just as well for dangles as for posts. All in all I am very pleased with this purchase. It came in a sturdy box and only one leaf was slightly crimped, which was easy to gently bend back into shape. And best of all - no more tangled mess of wires and hoops to sort out each morning!

Great earring tree!I
Color: Silver, Color: Silver
I like this earring tree more than I’d expected to! It holds a lot of earrings, is very sturdy and stable, and cute. It also has a little nest basket where you can put items like bracelets and rings. I love that I can see my earring options, and find the ones that best go with my outfit when getting ready for work in the morning. I’m glad it’s metal, almost a work of art, vs cheap plastic. It’s a pleasure to look at, not just functionally useful.

Exactly what I wanted!
It is really exactly what I was looking for. I've been living with my jewelry in ziplock bags since we moved over here and everything fits perfect. I saw some reviews that claimed it was unstable but I tested it and it seems sturdy though I'm not hanging heavy pieces. It is a nice size and I love the little ring basket. It also feels pretty decent quality too. Glad I got the black one as I'm not sure where I have it that the copper/bronze would look right. I think it is elegant, practical and I wish I could post a photo with my pieces on it to show that it really holds things beautifully.

Looks great by my bed!
Even my boyfriend keeps commenting how much he likes it. It's a usable piece of art! I will comment that the earring holes can be a little tricky since the leaves are turned all different ways. You have to be strategic with how you line up your long/dangle-y earrings with your studs so everybody fits and can be seen. A little tricky. But not a deal breaker - especially when it's so easy on the eye. The other slight negative is that this really isn't the best necklace holder. I would have thought, "No problem!" But it's a bit awkward. Especially if you actually intend to see all your earrings. You'll end up hanging most of your necklaces from the top most branch - but they slide down into the crevice to stay. Then you've got a lot of overlapping. And trickiness to retrieve the exact necklace you want with ease. However, this is still a fabulous earring tree. I can't say enough good things about it. Love the little basket for miscellaneous. Hair bands, lip gloss, etc.

Beautiful jewelry display
Color: Bronze-Tone
A few rough edges, but all in all well made and attractive. Holds lots of earrings and I can drape my necklaces on the tree. There's a nice bowl for bracelets and a nice tray that forms the base.
