Edelbrock Precision-Flow 42 lb/hr High-Impedance Fuel Injector - Part Number 3294

These new Precision-Flow high-impedance fuel injectors deliver the outstanding idle quality, unparalleled flow consistency, and durability essential for high-performance EFI applications. With a flow rate of 42 lb/hr (440cc/min) at 43.5 psi (3 BAR), these are the same high-quality fuel injectors used in the Edelbrock Pro-Flo 4, 675 horsepower-rated EFI Kits. Engineered for excellent response and fuel atomization, Precision-Flow Fuel Injectors are manufactured and 100% flow tested to maintain the tightest tolerances in the industry. They undergo a multi-point dynamic flow testing process to ensure they meet the stated flow rate within +/- 2%. Testing at multiple pulse widths, rather than just at static flow, ensures consistent cylinder-to-cylinder fuel delivery throughout the entire operating range of an engine, not just at maximum capacity. The result is a smoother-running engine that is easier to tune and maintains a consistent cylinder-to-cylinder air-fuel ratio. They are a short-body style injector using a USCAR-style connector with a standard .550” O.D. lower O-ring and measure 1.480” from O-ring to O-ring. These injectors are designed for pre-pollution-controlled or race applications only. Available as single injectors or in sets of 8, these Precision-Flow fuel injectors are the final piece of your fuel delivery system in any EFI-equipped application. These new 42 lb/hr Precision-Flow high-impedance fuel injectors undergo multi-point dynamic flow testing to deliver outstanding idle quality, unparalleled flow consistency, and durability essential for high-performance EFI applications.

• Ensures that the injectors deliver the required fuel flow throughout their operating range and not just at max flow
• Maximizes fuel efficiency for clean, complete combustion
• Consistent fueling from cylinder to cylinder
• Multi-point Dynamic Flow Testing
• Excellent Fuel Atomization
• Flow matched to 2%
