Holley Introduces Terminator Stealth EFI


New from Holley – the Terminator Stealth EFI system. This system offers the classic looks of a carburetor combined with the customizability of electronic fuel injection, and will support up to 600 hp. See more details below.

Official Release:

Holley Performance Products is pleased to announce our all-new Terminator Stealth EFI, which provides the classic, traditional look of a carburetor with all the tuneability and driveability of electronic fuel injection. Terminator EFI will support any engine with an output of 250-600 horsepower that has a 4150-style intake flange. These systems give you all the same self-tuning features you’d get with any Holley Terminator EFI system – in a stealthy new package.

Terminator Stealth EFI is easy to install – no computer experience is required, and you don’t need a laptop to use it. It comes complete with an easy-to-use full-color handheld touchscreen, and all you have to do is answer a few simple multiple-choice questions. It’s even upgradable to complete laptop control. Terminator Stealth EFI is available in three distinct finishes – polished, Hard Core Gray and traditional Dichromate look. Plug-and-play harnesses and minimal connections ensure a fast, easy installation.
