New for the Sniper EFI product line is a factory replacement Sniper EFI canister style ignition coil. This ignition coil is potted with a premium grade epoxy, making it perfect for high vibration environments and can be mounted in any direction (horizontal, vertical, or upside down). No oil fill means no failure for multiple mounting positions. The new Sniper EFI canister coil is perfect for anyone wanting to upgrade their ignition system while maintaining a factory look under the hood.


  • Metal canister is epoxy filled to protect the internal coil windings from high vibration applications
  • Improved output coil for electronic ignitions, and MSD Ignitions (ballast resistor required for points)
  • 100:1 turns ratio and lower primary resistance produce high voltage output
