Overview
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.

Orange looking, but large capacity
Size: One Size, Color: Brown
I ended up returning this product, it looks more orange in color than what is pictured. Also, it doesn't smell like leather. On a positive note, it was inexpensive and did have a large organization capacity.

Best wallet on the market.
Size: One Size, Color: Nubuck Black, Size: One Size, Color: Nubuck Black
This is the only wallet I buy now. Over and over. I like simple wallets. No bifold. Trifolds hurt your back. Hard case are a mess that rub your credit card mag strips off from friction. I found this a few years back and have bought 3. I am a stone worker so mine get worn from the dust and grit in my pockets faster than normal wear and I need to swap them out every couple of years. I like the simplicity and the fact that the pockets are stitched the same depth so your cards stack like varying length stair-style tabs rather than all the same depth. Wallet is RDIF protection lined. I can put like 15 cards in this wallet and it’s still thinner than a bifold holding 5. I love it. I mean it. I haven’t found a better wallet than this one. They are very well-built. Picture shows wallet with 19 cards + 40 dollars. 3/4 of an inch thick.

Good product although the leather is a bit stiff. Hopefully it will soften up over time. Fair price, fast shipping…
