Description

The Holley EFI 66 lb/hr Performance Fuel Injectors are a set of eight Bosch/EV1 style injectors engineered for high-performance applications requiring precise fuel delivery. These injectors boast a flow rate of 66 lb/hr at 43 PSI, with a low impedance (2.2 Ohms) design suitable for peak and hold drivers. They are capable of supporting up to 1050 horsepower and feature a tri-cone spray pattern to ensure efficient fuel atomization. They are compatible with E-85 and gasoline fuels. Each injector includes necessary O-rings for installation. It is important to verify compatibility with your specific fuel system and ECU before ordering, as proper tuning is required to optimize performance and ensure safe operation. These injectors are legal for sale and use on Uncontrolled (Non-Emissions Controlled) Vehicles, which include vehicles from 1965 and older (U.S. manufactured California Certified), 1967 and older (U.S. manufactured Federally Certified), and 1967 and older (Foreign manufactured). Installation on Emissions Controlled Vehicles is prohibited by law.
