Holley Sniper 2 EFI Self-Tuning Fuel Injection Systems

Holley Sniper 2 EFI self-tuning fuel injection systems are perfect for street rods, muscle cars, off-road trucks, or nearly any carbureted vehicle. They can put an end to cold start issues, hesitations, vapor lock, and flooding. The systems are available in standard tuning kits—or the Master kit that includes an external fuel pump. Choose from a polished or satin black finish on the throttle body.
