I don't think there is much performance to be had there, but with that said, I tried the red MSD ones mainly for the cool look, but then realized the writing would be upside down on the 6.2, and they changed the logo to a much smaller size and stopped the white letter contrast, which was the look. I sent it back without install.

Unfortunately I really question whether you get any performance advantage, especially for the price...
I contemplated it for my daughters 6.4 when she was having some issues... easily a couple hundred bucks and with the dual plug design I don't know if it would be any help....

Can't say on the Hellcat, but on the previous gen upgraded coil packs were tested and actually showed a LOSS in power. The red looked cool though.

I've got a set of Sultans of spark but have not installed them yet. Looks like a bitch as far as clearance.

Why do you think that is?

getting more spark at a lower rpm, no need for the higher rpm. 80k x 2 plugs pretty good burn I'd say.

That doesn't make sense. I've installed hot ignitions on a lot of my hot rods and never experienced lower idle.

Does not the ECM command the idle speed?

Well, I since have experienced a 2mpg gain in mileage, Instantaneous starting, and throttle response. and zero problems my kid swears by them and after all, it was a gift. and currently pushing 900rwhp with 965rwtrq on ms109 on HO mode so I'm happy.

I don't doubt that these coil packs work as I will be installing them. I just question the lower idle. Fuel would have to be lowered. The coils add timing.

So the only ones that have shown any promise are the granatelli with the 80000 volts?

After talking to the guy at DUI, I bought their coils. I have not installed them yet as it looks like a bitch with my shock tower brace installed.
