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. We took everything that we learned from the original Sniper EFI system and added 14 new features that will make your EFI conversion more simple, reliable, and modern. 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. If you're looking for a high-performance fuel injection system that delivers power, efficiency, and ease of use, look no further than the Sniper 2 EFI.

Not worth the time
Color: Light Brown, Size: 4
Plastic pieces for the dry wall broke and also created an even bigger hole in the wall. One of the shelves wouldn’t even stay level despite following all instructions. Wood gives you splinters as well since it’s not sanded down.

Beautiful room dividers! I'm glad I bought several.
Color: Light Beige, Size: 6-Panel
This room divider is perfect for my use. I bought one with 6 panels and another with 4 panels, mostly to hide areas of my living space when guests come over. The screens are attractive, a pleasing color, just the right height and width, and a very pretty design. They require no assembly and are easy to put in place. When not in use, they store in a compact fashion.
The only drawback is the odor from the manufacturing process. I left the screens on an enclosed porch with the windows open for about two weeks before I could tolerate the odor inside the house. After that, there was no problem.

Just the features I needed
Color: Light Beige, Size: 6-Panel
Product was exactly as described and just what I needed to set up a guest room that has a double tinted glass door.facing the font and a road 50 yards away. The glass tint allows people to see inside after dark and interior lights are on, so I needed a very lightweight screen to put up across it for privacy at night and did not want curtains over my showpiece doors. The screen folds neatly and stands up beside an armoire out of sight when not needed, but steps away at night to put up until morning. Lightweight but sturdy—just what I was looking for. Looks high end.
