220 PPH Fuel Injectors 8-Pack

The 220 PPH Fuel Injectors 8-Pack from HOLLEY represents a critical upgrade for engine builders, tuners, and performance enthusiasts seeking reliable fuel delivery at higher fuel volumes. These high-impedance injectors are designed for naturally aspirated and moderately boosted applications where stock injectors fall short of volumetric demands. Whether you're building a street machine, track car, or daily driver with forced induction aspirations, this eight-piece set provides the flow capacity needed to support increased horsepower without sacrificing drivability or cold-start characteristics.

At 220 pounds per hour (lb/hr) flow rate, these injectors deliver precise atomization and metering across the entire fuel map, a critical factor in preventing lean-out conditions under sustained acceleration or boost. The high-impedance design ensures compatibility with most stock and aftermarket engine control units without requiring external resistor boxes, simplifying harness integration on retrofit installations. The universal EV6/PICO USCAR connector configuration makes these injectors adaptable across multiple platforms, from LS engines to carbureted conversions fitted with EFI systems, eliminating the need to source platform-specific units.

Professional installers and experienced DIY builders appreciate the 8-pack quantity, which covers full fuel rail coverage on eight-cylinder engines or provides spare units for R&D tuning sessions. Installation requires basic fuel system knowledge—proper fuel pressure regulation (typically 43.5 PSI for this flow class), quality fuel filters, and synchronized injector pulse width tuning via your ECU's base fuel map. These injectors perform optimally when paired with a quality fuel pump, regulator, and tuned ECU parameters that account for injector dynamics and engine displacement.
