These are generally used with the Holley EFI systems.

It's the Pantera IGN-1A coil, everyone seems to be re-selling them these days.

There have been a few threads on such topics....answers ? more questions really lol

Some say the 585's are hotter than other LS coils...and they probably are. Some report power gains.
Some say the Firecore 585/IGN-1A's are hotter again.....but will that mean another power gain ?

Then the full IGN-1A is more powerful again....so does that mean another power gain ?

Where do the gains stop and finish ? How much spark is not enough...and too much ?

Despite not knowing or believing....I've bought 8 myself to try LOL. Havent fitted them yet though.

But they're undoubtedly one of the most powerful coils of it's type around, and I know they're used on one low 6s car here in the UK ( not LS )

But then stock coils have also went insanely fast and made shitloads of power.
