Do you need to upgrade your ignition system due to a recent Sniper EFI installation, but have no idea which option is best? The HyperSpark 2 is what you are looking for. It is a direct upgrade for existing HyperSpark ignition box, featuring a smaller form factor and hotter spark, or pairs great with Sniper EFI installations. This low profile box can fit nearly anywhere inside of your engine bay or cockpit. The HyperSpark 2 ignition box packs all of the proven features of its predecessor into a smaller form factor package, making it easier to mount, providing the cleanest installation possible. This ignition box packs up to 150mj of spark energy when used with its matching ignition coil, PN 556-152, resulting in enough energy to safely fire your Sniper EFI engine combination.

Features:

  • Designed to work with Sniper EFI, Minimal wiring required.
  • Plug and play with existing HyperSpark installations, or Sniper EFI HyperSpark Main Harnesses (PN 558-328)
  • Includes an ignition harness for fresh Sniper EFI Installs simply wanting to add timing control
  • New processor and board design provide a highly efficient ignition, minimal heat and max spark energy with less current draw
  • High RPM operation and maximum output using the HyperSpark Ignition coil (PN 556-152)
  • Powerful capacitive discharge of multiple sparks improves performance, and ensure complete combustion
  • Consistently high spark energy of 135mJ to 150mJ for every firing, from idle to redline rpm
  • Operates on most 7 to 28-volt electrical systems
  • Fully protected against an open coil, shorted coil and open load
  • Quickens throttle response and improves starting
  • Tach Output to drive an external Tachometer
