Description
Want to make the switch from the original Sniper EFI to Sniper 2 and don't want to rewire your system? The new Holley Sniper 2 fuel injection upgrade kits are designed to do exactly that! Included with each Sniper 2 plug-and-play upgrade system is an adapter solution that connects your existing Sniper EFI wiring harness to a Sniper 2 throttle body in minutes. Simply remove your Sniper EFI throttle body from the intake manifold, unplug all connectors, reinstall the Sniper 2 throttle body, and plug the Sniper EFI 2 adapter harness into your existing main harness. Cycle your ignition key, run a fresh wizard on the display of your choice, and enjoy the benefits of Sniper 2 EFI.
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. Holley took everything that they learned from the original Sniper EFI system and added 14 new features that will make your EFI conversion simpler, more 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.
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 self-tune with no laptop or tuning 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. Four total upgrade kits are available: polished and black, with or without external fuel pressure regulator (required for Sniper 2).
