Experience the enhanced #1 EFI conversion system – introducing Sniper 2 EFI, a self-tuning, user-friendly EFI conversion designed for common 4-barrel (4150 flange) style carburetors. Building on the success of the original Sniper EFI system, Sniper 2 incorporates 14 new features for a simpler, more reliable, and modern EFI conversion. As part of the comprehensive Sniper Ecosystem, it seamlessly integrates with Hyperspark ignition, complete fuel systems, various user interfaces/dash displays, and more.
A noteworthy addition to Sniper 2 is the optional Power Distribution Module (PDM), an affordable accessory consolidating EFI and ignition wiring into a user-friendly location. With minimal wiring connections – Battery+, Battery-, Switched Ignition, and RPM – this system simplifies the setup process.
Transform your classic into a modern, fuel-injected vehicle with easy cold starts, smooth drivability, and improved fuel economy. Sniper 2 is designed for at-home installation in your garage, supported by Holley's comprehensive installation manual and videos. The user-friendly setup wizard requires answers to a few simple questions about your engine to initiate self-tuning – no laptop or tuning experience necessary.
If you seek a high-performance fuel injection system delivering power, efficiency, and ease of use, Sniper 2 EFI is your ideal choice.
