42 PPH Fuel Injectors 8pk High Impedance

The 42 PPH Fuel Injectors 8pk High Impedance from HOLLEY is designed for carbureted-to-fuel-injection conversions, street performance builds, and naturally aspirated engine applications that require precise fuel delivery at moderate flow rates. These injectors are ideal for small-block engines, LS platforms, and classic muscle car restorations, providing reliable atomization without oversizing.

With a flow rate of 42 pounds per hour, this eight-pack configuration offers complete coverage for a V8 engine, allowing for future modifications or component swaps. The high impedance design ensures compatibility with standard ECU outputs and existing wiring harnesses, eliminating the need for costly resistor boxes or controller upgrades during installation. The optimized injector tip geometry and internal valve seat enhance spray pattern consistency across the full RPM range, preventing lean spots and hot spots.

Engine builders and installers favor this injector set for mild to moderate performance builds, including road-course engines, weekend cruisers, and truck restorations where reliability is paramount. Compatibility extends to most popular EFI manifold designs, including LS swap configurations and retrofits on classic carbureted platforms, making it a versatile choice for various applications.
