Description

The 42 PPH Fuel Injectors 8-Pack by Holley is an essential upgrade for builders and enthusiasts tuning carbureted or early fuel-injected platforms. These injectors are designed specifically for naturally aspirated engines, where consistent and reliable fuel metering is crucial for optimal throttle response and driveability.

Rated at 42 pounds per hour (PPH), these Holley injectors provide precise fuel flow tailored for moderate displacement engines. They are engineered for high atomization quality and spray pattern consistency, ensuring improved performance. The high-impedance design allows for direct ECU control without the need for external resistor packs, simplifying installation and tuning.

Street rodders, classic car restorers, and performance tuners will appreciate the reliability and compatibility of these injectors with Holley EFI systems and aftermarket ECUs. This 8-pack format ensures a complete setup for multi-point fuel injection systems, making it a practical choice for various performance builds.
