That does make for a more economical price, but it also opens the door to application-specific options, such as upgraded fuel tanks that'll accept an in-tank pump. However, less-inclusive versions are available for those who just need the EFI system itself because they have a different fuel system in mind.

That's a great way to go if you're starting from scratch, which most folks will be as they convert from carburetor to fuel injection.

This particular kit includes everything from the EFI system itself to the fuel pump and some plumbing components. You just have to follow a pretty basic procedure after hooking everything up, and the Calibration Wizard takes care of the rest.ĭifferent kits are available to shorten the shopping process as well. It's also a self-learning system, meaning you don't need to be a tuning expert to get it running. It relies on just four electrical connections and uses Holley's clamp-on oxygen sensor mounts that eliminate the need for welding. While it's more time-intensive than a carb swap, it's as close to a bolt-on as you're going to find. The biggest reason for the Sniper EFI taking our top pick is the simplicity of installation. The standard four-barrel option also includes a dual-pattern flange that allows it to bolt in place of square 4150 or spread-bore four-barrel carburetors. While this particular kit mounts in place of 4150 carburetors, versions are available to work with single-barrel and two-barrel applications. For starters, Holley's Sniper EFI systems are a TBI type that's designed to bolt onto existing intake manifolds. Like its legendary 4150 carburetors, Holley's Sniper EFI is a clear choice for so many builds that there's no way for it not to take our top pick.
