The Dominator EFI Kit for GM LS engines by Holley provides a complete bolt-on fuel injection solution designed for LS engine swaps, restorations, and performance builds. This kit simplifies the transition from carbureted systems to modern sequential multi-port electronic fuel injection, making it ideal for classic muscle cars, hot rods, and vintage trucks.
Featuring a Holley EFI fuel pump module, precision fuel injectors, a high-flow fuel rail assembly, and a complete wiring harness with integrated engine management electronics, this system ensures factory-style reliability. The adaptive fuel delivery mapping enhances cold-start performance, idle quality, and fuel economy, providing a significant advantage over traditional carburetors.
The modular design allows for staged tuning through Holley's EFI software platform, enabling users to refine air-fuel ratios and ignition curves without needing to swap physical components. This kit is perfect for enthusiasts looking to maximize the performance of their GM LS engine builds.
