Sniper EFI

Sniper EFI is a product line from Holley that offers electronic fuel injection (EFI) systems designed to replace traditional carburetors. It was introduced in 2016 to make modern fuel injection more accessible for classic cars and trucks.

These systems are known for being self-learning and easy to install, often requiring only a few wiring connections and no laptop. They use sensors (like a wideband oxygen sensor) to automatically adjust the air/fuel ratio, improving engine performance, fuel efficiency, and drivability.

Sniper EFI is popular among enthusiasts because it provides the benefits of modern EFI—such as better cold starts, smoother running, and more reliable performance—while still fitting on engines originally designed for carburetors.
