Fuel Injector Spacer Set of 8

The Fuel Injector Spacer Set of 8 from ICT BILLET is engineered for LS-series engine builders and performance enthusiasts seeking precise fuel injector positioning and optimized spray patterns. These aluminum adapters address a critical need in modern LS engine fuel system tuning: maintaining proper injector height and angle when upgrading to different fuel rail configurations or custom intake manifolds. As an experienced mechanic, you know that injector height directly affects fuel atomization, combustion efficiency, and engine response—making these spacers essential for any serious LS platform modification.

Machined from high-grade aluminum with integrated O-ring seals, the Fuel Injector Spacer Set of 8 delivers reliable, leak-free performance under high fuel pressure. The natural finish preserves the aluminum's corrosion resistance while maintaining excellent thermal conductivity—critical for fuel rail environments where heat management affects fuel temperature and system stability. Each spacer in this eight-piece set features precision-engineered O-ring grooves that ensure consistent sealing across all eight cylinders, eliminating the risk of uneven fuel distribution that can cause lean/rich conditions and spark knock. The compact design (3.9 x 0.8 x 6.35 inches) integrates seamlessly into tight engine bay configurations without requiring extensive modifications to existing fuel rail assemblies.

This set is ideal for LS1, LS2, LS3, and LSx engine swaps, particularly when adapting aftermarket fuel rails, custom intake manifolds, or transitioning between OEM and performance fuel system components. Whether you're running a mild street build or a high-horsepower race engine, proper injector spacing prevents flooding, vapor lock, and uneven cylinder fueling—all common issues when fuel system components aren't precisely matched. Installation is straightforward: remove the original fuel injectors, install the spacers with new O-rings, then reinstall injectors into the spacered bores. Professional installers and home builders alike rely on ICT BILLET's precision tolerances to maintain EFI system integrity across the RPM band.
