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