Sniper, Sniper 2, and Terminator X Components

Sniper, Sniper 2, and Terminator X Components

We originally created this page to list upgrade and replacement components for the popular Sniper EFI systems. However, when Terminator X arrived, it turns out that they share many of the same components--particularly on the Terminator X Stealth throttle bodies. And now we are excited to offer components and accessories for the new Holley Sniper 2.  Don't see it here? Not clear if it fits your EFI system? Use the fly-out at right to get support or visit our Contact Us page!

Are you looking for service components for the original Terminator EFI System (the one that pre-dated Terminator X)? You can find those here.

Note:  References to "Sniper" without a numeral should be assumed to reference the original Sniper.
