LAS VEGAS, NV — The aftermarket EFI wars have heated up over the past few years. Competition has caused the sheer amount of aftermarket EFI systems to proliferate, making them more affordable than ever.

With that in mind, Holley talked up its latest EFI, the Sniper EFI Stealth system last week at the 2019 SEMA Show in Las Vegas, NV.

Modeled after an Ultra HP carburetor, the Holley Sniper Stealth 4150 has four 100 lb./hr. fuel injectors, a dual-feed configuration, and supports up to 650 horsepower naturally aspirated.

From the fuel bowls to the wiring harness exiting the back of the system to stay hidden, the Sniper delivers EFI advantages while showcasing a vintage vibe.

Holley says the Sniper EFI Stealth product line (including the previously released 4500 series) is packed with plenty of modern performance features, including a high-pressure fuel crossover line, rear exist wiring for easy routing, and a timed spark port located under the front injector cover (fuel bowl).
