Affordable fuel-injection

4 wire connection

Installing a modern electronic fuel-injection system to your classic car just got simpler with this Holley Sniper EFI. This kit is a basic bolt on carburetor replacement with everything mounted to the throttle body itself. While the Sniper EFI System is easy to install it will support up to 600 horsepower with a simple 4 wire connection (Battery +, battery -, switched ignition and RPM). There are no extra control boxes to mount that will clutter up your engine bay and both the fuel pressure regulator, ignition timing control are completely integrated. All of this is controlled by an included color touchscreen programmer for a simple setup. Simply answer a few basic questions about your car and the parameters for your application are loaded and you’re ready to go! The self-tuning ECU will automatically make adjustments on the fly which means no laptop required. Available in black ceramic or shiny finish.
