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. The Sniper EFI 2x4 was designed for use on naturally aspirated engines, while the Super Sniper EFI 2x4 system was developed for naturally aspirated, draw-through supercharged, and blow-through turbocharged applications.
