120 PPH Fuel Injectors 8pk High Impedance

The 120 PPH Fuel Injectors 8pk High Impedance from Holley is designed for carbureted and EFI conversion applications where precise fuel atomization and reliable flow characteristics are essential. These injectors cater to automotive enthusiasts and builders working on classic muscle cars, street rods, and performance builds that require consistent fuel delivery across varying engine speeds and load conditions.

With a flow rate of 120 PPH, this injector set is suitable for naturally aspirated engines in the 400–600 horsepower range, making it an excellent choice for mid-level performance builds and restorations. High impedance injectors operate at 14–16 ohms resistance, allowing compatibility with stock and affordable aftermarket ECUs without needing a dedicated injector driver module. This design simplifies wiring and reduces installation complexity for retrofit fuel injection systems.

Builders upgrading their fuel systems will benefit from the optimal fuel atomization and combustion efficiency provided by these injectors, preventing lean-out conditions that can compromise drivability and damage engine components. Holley's manufacturing standards ensure tight spray pattern consistency across all eight injectors, eliminating the risk of lean or rich cylinders that can occur with lower-quality alternatives.
