Description

The Sniper-2 Upgrade Kit Black from Holley represents a modern approach to carburetor replacement and fuel system optimization for street and performance vehicles. This complete throttle body assembly is engineered for builders and enthusiasts who demand precision fuel metering, drivability, and reliability without the complexity of traditional carburetors. Whether upgrading a classic hot rod, restomod, or contemporary engine swap, the Sniper-2 EFI platform delivers sequential port injection control in a bolt-on package that fits square-bore intake manifolds.

Built from aluminum and finished in durable black powder coat, the Sniper-2 throttle body integrates Holley's proven EFI architecture into a compact, self-contained unit that mounts directly where a carb would sit. The square-bore design ensures compatibility with a wide range of intake manifolds while the sealed aluminum construction resists corrosion and maintains consistent air and fuel distribution across all engine speeds. Advanced fuel injection control enables precise mixture mapping, cold-start optimization, and tuning flexibility through Holley's standalone ECU logic—eliminating stumbling, hesitation, and the lean-out issues common to carbureted platforms.

Mechanics and engine builders favor the Sniper-2 EFI kit for street applications where cold-weather starts, part-throttle response, and fuel economy matter as much as peak power. Installation requires basic electrical wiring, fuel supply plumbing, and intake manifold bolt-on fitment—no custom fabrication needed for most applications. The kit's compact dimensions (12.4 x 9.3 x 14.6 inches) and modest weight of 9.95 lbs make it ideal for retrofit projects where space is tight or where traditional carburetor clearance is problematic. Verify manifold compatibility and fuel system pressure rating before ordering to ensure seamless integration with your specific engine platform.
