Supports up to 1250 HP with 8x 100 Lb/Hr Injectors

Introducing Sniper EFI 4150 2x4! Looking to convert your draw-through dual carbureted blower engine to EFI? Do you have a Tunnel Ram with dual quad carbs? Are you putting together a twin-turbo blow-through setup? Look no further! The Sniper EFI 4150 2x4 system from Holley features 8, 100LB/HR Fuel Injectors capable of supporting 1250 HP on both naturally aspirated and forced induction applications.
