Anyone here tried a hotter coil for thier 4.0 or for that matter any other engine.
Feelings?
I'm thinking about increasing the gap on my plugs and running a hotter coil.
Not quite up for the multispark conversion, but who knows.

I wonder about the MSD replacement coil #8228. It's supposedly drop-in part same connector/bolt pattern.
Primary Resistance: 1.2 ohms Secondary Resistance: 13.7K ohms Maximum Voltage: 35,000 volts Inductance: 8 mH Turns Ratio: 70:1
That reads (resistance wise) like the factory Toyodenso coil
1.2 primary, 13.7 secondary but I don't have any reference for what the stock coil puts out. Drawing from transformer theory my guess is it's a damn close match... wow .. Digital CPC (direct fire) systems too.
Heh.. ..mebby not..
I have the Accel SuperCoil in my 4.2.
It 'seemed' to give me some extra punch when I put it in.

I don't know about that....
When I went to a hot Accel coil, I also went with their fancy cap that is supposed to limit cross fire. I burned it up in a couple weeks, literally. I then went to Chrysler and got an OEM cap. It has lasted 3 years.
