Delivering up to 900 horsepower worth of airflow, the XFlow throttle body is designed for big power builds without sacrificing everyday drivability. Its 8-injector design supports higher fuel demands, while the self-learning ECU continually refines fueling to match real-world driving conditions—giving you smoother starts, better throttle response, and increased efficiency.

Perfect for enthusiasts upgrading from traditional carburetors, the Holley XFlow bolts onto most 4150-style intake manifolds and features integrated sensors, a handheld touchscreen for tuning, and advanced ignition control. No laptop tuning required—just a simple setup and go.

Each Sniper X Flow kit includes everything you need to convert your setup, from fuel injectors and sensors to gaskets and wiring, making installation fast and hassle-free. The system also supports boost and nitrous timing tables, making it ideal for power-adders and performance applications.
