Black Jack Pro Series Ignition Coils

Works great, easy install, wish it worked without timing control on through the ecu but thats a personal preference

I knew moving from a Carburetor to EFI was going to be a challenge. But Aces components have made the move fairly painless. I wanted to run an ignition coil that would be compatible with the Killshot EFI system I was installing and ordered the Black Jack Pro series coil. Working out the tuning required a learning curve but the coil has been wonderful.

HEC spark makes sense fir my built, works great
