Sniper 1 to Sniper 2 Upgrade kit with External Fuel Pressure Regulator, Fittings, Hose
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. | Want to make the switch from the original Sniper EFI to Sniper 2 and don't want to rewire your system? The new Sniper 2 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. | 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. | 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.
