Holley Sniper 2 4150 EFI Master Kit with 5” Handheld Display/ Fuel Pump/ PDM

For easy cold starts with a smoother throttle feel, upgrade your 4-barrel carburetor to the Sniper 2 EFI master kit! Holley designed this kit with ease of use in mind as it features a calibration wizard. Just answer a few questions about your setup and it’ll start self-tuning while creating a base map. This means even inexperienced tuners can use it, all without the hassle of using a laptop. For more in-depth tuning, though, users can set up customizable parameters through the 5” handheld display. Backlit for easy viewing, it makes tracking your vehicle’s performance simple with the added benefit of a built-in GPS speedometer.

It makes the switch easy on the fuel system as well since it includes an external, inline fuel pump. Even wiring is simplified thanks to the PDM, which isolates the EFI’s core and allows seamless compatibility with ignition systems. Drivers have the choice between a black or polished finish to make their engine bay pop while the “hidden” harness maintains an organized look.
