Sniper EFI Hyperspark-2 Ignition Box

The Sniper EFI Hyperspark-2 Ignition Box from Holley is a modern digital CD ignition system engineered for enthusiasts building or upgrading high-performance EFI-equipped engines. This compact ignition box serves as the brain of your engine management system, translating sensor data into precision spark timing that maximizes combustion efficiency, throttle response, and overall reliability. Whether you're tuning a street engine or competition platform, the Hyperspark-2 delivers the timing control necessary to extract maximum power while maintaining stable operation across varying load and RPM conditions.

Built with Holley's proven digital architecture, the Sniper EFI Hyperspark-2 Ignition Box features capacitive-discharge (CD) ignition technology that generates a strong, consistent spark across the entire RPM range. The black anodized aluminum enclosure houses sealed electronics protected from moisture and vibration, critical for underhood reliability. This unit integrates seamlessly with Holley's Sniper EFI fuel injection platform, allowing real-time spark advance correction based on engine load, coolant temperature, and intake air temperature for optimal combustion in all conditions.

Engine builders, performance shops, and serious DIY enthusiasts benefit most from the Hyperspark-2, particularly those running carbureted or EFI-converted engines requiring adaptive ignition management. The compact form factor—measuring 6 x 2.8 x 10.7 inches and weighing just 1.57 lbs—allows flexible mounting in tight engine bays. Installation requires connection to your Sniper EFI harness and compatible coil pack, making it a straightforward addition to complete EFI systems. This ignition box is ideal for street, strip, and off-road applications where precise timing control directly impacts throttle response, fuel economy, and power output.
