    HOLLEY SNIPER EFI XFLOW 1375 - BLACK CERAMIC

    Supports up to 1375HP on boosted engines with 8x 120lb/hr injectors!

    Introducing Sniper EFI XFlow! Looking to convert your blow through carbureted turbo engine to EFI? Look no further! The Sniper EFI XFlow 1375 from Holley features eight 120 LB/HR Fuel Injectors and flows 900CFM allowing it to safely support up to 1375HP with forced induction!

For applications making more than 21.5 psi, there are three additional 0-5v Sensor Inputs which can be used for an external MAP Sensor, Dome Pressure for boost control, and/or oil pressure and fuel pressure sensors. An External Fuel Pressure regulator is required; we recommend part number 12-851 for Forced Induction applications.
