The Sniper EFI Hyperspark Ignition Coil by Holley is engineered for high-performance EFI-equipped engines that demand reliable spark delivery and consistent ignition timing. This universal ignition coil suits builders and technicians upgrading carburetor or early electronic fuel injection systems to modern EFI platforms, or replacing failed coils in existing Sniper EFI installations. The coil's robust design ensures stable operation across a wide RPM range, making it essential for street engines, mild performance builds, and show cars where dependable starting and smooth idle quality matter.
This E-Core ignition coil generates 43,000 volts of spark energy, sufficient to fire premium spark plugs under high-load conditions and extended electrode gaps. The 0.441-ohm primary resistance is optimized for Sniper EFI ECU output specifications, ensuring efficient energy transfer and reducing heat buildup during extended operation. The coil features a male HEI connector for straightforward integration into Sniper systems and includes a 90-degree boot with integrated terminal, allowing flexible wiring routing in tight engine bays. Its compact dimensions (4.8 x 4.1 x 6.9 inches) and lightweight construction (2.7 lbs) facilitate mounting near the spark plug or remote location without significant thermal or mechanical stress.
Engine builders choosing the Sniper EFI Hyperspark Ignition Coil benefit from Holley's reputation for precision ignition components and seamless Sniper EFI system compatibility. The universal design accommodates various small-block and big-block applications, from Chevrolet to Ford platforms, making it a practical replacement or upgrade component. Installation requires basic mechanical knowledge: the HEI connector simply plugs into the Sniper ECU ignition output, the 90-degree boot positions the spark wire optimally, and the coil mounts securely using existing engine block bosses or fabricated brackets. For optimal performance, verify your Sniper EFI system firmware is current and confirm coil mounting location minimizes exposure to extreme heat sources.
