Description

Direct upgrade for existing HyperSpark ignition box, Holley Sniper EFI HyperSpark 2 CD ignition boxes feature a smaller form factor and hotter spark. These low-profile boxes can fit nearly anywhere inside of your engine bay or cockpit. They have all the proven features of their predecessor in a smaller package, making it easier to mount, providing the cleanest installation possible. HyperSpark 2 ignition boxes pack up to 150 mJ of spark energy when used with the matching ignition coil, resulting in enough energy to safely fire your Sniper EFI engine combination.

Features:

* Plug-and-play with existing HyperSpark installations, or Sniper EFI HyperSpark main harnesses
* 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 maximum spark energy with less current draw
* High rpm operation and maximum output using the HyperSpark ignition coil
* Powerful capacitive discharge of multiple sparks improves performance and ensures complete combustion
* Consistently high-spark energy of 135 to 150 mJ for every firing, from idle to redline rpm
* Operates on most 7 to 28 V electrical systems
* Fully protected against an open coil, shorted coil, and open load
* 1.47 lbs. lighter than an original HyperSpark ignition box
* Quickens throttle response and improves starting
* Tach Output to drive an external tachometer
