Our HyperSpark Master Kits were designed to make upgrading your ignition on a Sniper EFI-equipped engine simple. When installed concurrently with a new Sniper EFI system, the combination creates the easiest to install EFI conversion on the market - only four flying lead connections required! This harness only requires one connection to a switched power source, battery positive, battery negative, and fuel pump power. The pre-terminated connectors and a built in 40A relay provides power to all of the components within the system. With the included Sniper EFI Main Harness you no longer need to run multiple wires to provide switched power for each individual component. This not only helps prevent wiring confusion, it will speed up your install time and clean up your engine bay. Just route the harness and pre-terminated connectors to your HyperSpark coil, distributor, and ignition box and plug them in.


  • Plug and Play Sniper EFI Main Harness replaces the standard Sniper EFI harness with four loose leads, Battery Positive, Battery Ground, Switched 12v, and Fuel Pump Power, for a simple and streamline installation
  • Designed for existing or new Sniper EFI installations. The HyperSpark Master Kit harness retains the same flying lead wire colors as the Sniper EFI main harness. New installations will not use the Sniper EFI standard harness or coil driver
  • Complete Ignition system in a box, including: HyperSpark Ignition Box, HyperSpark Ignition Coil, HyperSpark Distributor (for your application), and a plug and play main harness
  • HyperSpark Distributors feature a Hall Effect crank trigger sensor providing a noise-free RPM signal to the Sniper ECU
  • Patented Clear Installation cap eliminates any confusion while installing the distributor
  • HyperSpark CD Ignition box is seal and powder coated to be installed in the harshest of locations
  • External LED on Hyperspark CD Ignition box helps verify 12v, cranking RPM, and low battery voltage
  • 135mJ of spark energy when used with the HyperSpark Ignition coil, ensures complete combustion
  • Integrated ignition coil bracket simplifies mounting the Ignition coil
  • Ignition coil connector removes any doubt of loose connections at the Ignition coil
  • Enables timing control on a Sniper EFI Installation
