Holley Sniper EFI provides one of the best and most economical ways to update the performance and drivability of your classic truck. Put an end to cold start issues, hesitations, vapor lock and poor throttle response. Sniper EFI gives you all the power and reliability of electronic fuel injection with none of the tuning issues commonly associated with carburetors.
With the self-tuning abilities of the Holley Sniper EFI, installation is as simple as removing your 4 barrel carburetor, installing the EFI, running fuel lines, answering a few simple setup questions on the handheld tuner, starting the truck and letting the EFI tune itself as you drive.
Wiring doesn't get any easier. It's a simple four-wire connection, and you don't have to be a computer whiz to use it. You don't even need a laptop. Just answer a few simple questions about your engine, and the Sniper EFI system automatically creates the base map and starts tuning on its own.
Supports 250-650 horsepower with four injectors. Features an integrated ignition timing control and coil driver. A high resolution, color 3.5" touchscreen is used for initial setup, tuning, and gauge display. Includes all necessary sensors, brackets and wiring, along with a thoroughly detailed instruction manual to ease installation and setup. Available in black or shiny, ceramic finish.
A high pressure fuel delivery system is required for operation of the Sniper EFI; #38-4510 Inline Fuel Delivery Kit is sold separately.
