Holley Sniper EFI 4150 Self-Tuning System Forced Induction 4 Barrel (4bbl) 1250 550-517

Looking to convert your blow thru carbureted turbo engine to EFI? Look no further than Holley for the Super Sniper 4150 EFI systems featuring 8, 100LB/HR Fuel Injectors capable of supporting up to 1250 HP on forced induction or dry nitrous applications. Is your combination not producing that much horsepower? No problem, Holley also offers a 650 HP four injector version for lower horsepower applications with a power adder or someone just needing additional sensor inputs. Did we mention the Super Sniper also has full nitrous control built-in? That's right, no need for a separate nitrous controller! Every Super Sniper EFI system also comes with a USB to CAN tuning cable, as well as free downloadable Sniper EFI Software to give you unlimited control of your engine.

Available in Shiny, Black Ceramic and Gold Finishes.  

This is a base kit, and doesn't include the complete fuel system: fuel pump, filters, feed and return hose and all fittings including fuel tank return line bulkhead fitting.  We sell the RobbMC Surge Tanks, and can provide the correct sized kit for your application (contact us for details).
