Description

The Holley Sniper 2 EFI is a self-tuning, easy-to-install EFI conversion system designed for common 4-barrel (4150 flange) carburetors. It includes 14 new features compared to the original Sniper EFI, aiming for simpler, more reliable, and modern EFI conversions. It integrates with the Sniper Ecosystem (Hyperspark ignition, fuel systems, displays). The system offers easy cold starts, smooth drivability, and improved fuel economy. Installation can be done at home with limited tools, and a user-friendly setup wizard creates a base map for self-tuning without a laptop.
