upgraded coil for a renix 4.0

[Oizarod115]

Does anyone know of a coil that is direct replacement for the Renix coil on a 4.0L? MSD seems to not make one.

 

or does anyone know if another coil will work but just not mount the same?

Accel, Mallory and MSD all made one at one point. Jacobs made one as part of their DUI system.

 

But all apparently no longer do....

if your truck is still rocking the original 20 year old coil, you should get a bump from a new stock one. :thumbsup:

yeah, I'm rockin the original one, think it might be having a heat-sink problem... i've got a bad miss after 10-20 minute heat soak at full operating temp. and occasionally a pretty good miss in dead stop traffic. seems to be random though not just one cyl and cap-rotor-wire-cranksens are all new mopar parts

 

figured if MSD made one for 40 bucks like they do for the HO (lucky bastards) i'd buy it :oops:
