Fuel Injector Set (8) 48PPH

The HOLLEY Fuel Injector Set (8) 48PPH is designed for engine builders and performance enthusiasts who require precise fuel delivery in high-flow applications. This set of eight injectors is ideal for naturally aspirated and boosted engines that need consistent atomization at specified fuel pressures. Whether you're tuning a street machine, building a competition engine, or upgrading a fuel system on a classic or modern platform, this injector set provides the metering accuracy necessary for stable idle quality and reliable performance.

Each injector in this set flows at 48 pounds per hour (PPH), optimized for mid-range displacement engines and moderate boost levels. The 48PPH flow rate ensures fine fuel atomization without excessive pressure drop, allowing your engine management system to achieve precise stoichiometric control across idle, cruise, and peak load conditions. HOLLEY's OEM-quality construction features durable internal components and reliable sealing, which are critical for preventing fuel leakage and maintaining consistent spray patterns during operation.

This matched set is particularly beneficial for eight-cylinder engines, especially those equipped with Holley carburetors or fuel injection manifolds. The direct bolt-in installation on compatible fuel rails minimizes complexity while ensuring proper seating and minimal modification. With a recommended fuel pressure of 35–45 PSI, these injectors are well-suited for a variety of performance applications.
