Bolt-on EFI systems have come a long way in the last decade, and Holley’s latest throttle-body system delivers
WHEN FACTORY ELECTRONIC FUEL INJECTION (EFI) FIRST HIT THE MUS TANG IN THE 1980s, MANY ENTHUSIASTS FELT IT WOULD BE THE DEATH KNELL FOR PERFORMANCE. Little did any of us know at that time that there was really nothing to worry about, and that we’d have Mustangs today rolling off the assembly line in excess of 400 horsepower (and more for specialty models like the supercharged Shelby GT500s from 2007-2013). Sure there were some problems early on as owners and the performance aftermarket figured out these OE systems and how to get the most out of them, and the same can be said for aftermarket bolt-on EFI solutions.
Over the years, the options to convert your carbureted engine to EFI have been many. From using the intake, injectors, wiring, and sensors from the ’87-’93 Fox Mustang to early throttle-body injection (TBI) units based off of GM truck units, there always seemed to be teething problems and a learning curve. However, over the last five years or so the bolton EFI game has really entered the next chapter, if you will, allowing anyone with basic mechanical abilities to be able to enjoy the benefits of modern fuel injection on their classic Mustang.
01 The Holley Sniper EFI system is a complete bolt-on EFI solution. All you have to do is supply an EFI-capable fuel system, which Holley can help you with as well. Included in the Sniper 4150 SelfTuning EFI kit is its cast throttle body (available in black, gold, or polished finishes), wideband O2 sensor, handheld touchscreen controller, and all necessary wiring—PN 550-511 is shown.
