The Dodge V10 engine used in the Viper and the trucks has two coil packs. One is a six cylinder coil pack for the front six cylinders. The other is a four cylinder coil pack for the rear cylinders. The six cylinder coil pack is the same thing you find in other Dodge six cylinder vehicles and in Dodge trucks. There's nothing really "performance" about it. The coils function identically to the coils on the Jeep coil rail. Most of the so-called "Viper" coils people put in Jeeps didn't come out of a Viper at all.

To do the mod, you have to rig up a bracket to hold the Dodge coil pack, install plug wires and extend the connector from the back of the engine bay to the new coil location. Doing that makes it marginally easier to check a single spark plug, but unless you're pulling your plugs every weekend, that's really a non-issue. I've had my coil rail off twice in the entire time I've had my 2000, and one of those times was for an engine swap.

But after you do the conversion you have plug wires, which are wear parts that need to be replaced periodically. And you have a spliced wire extension to get the computer's commands to the coil pack. You're introducing more places for failure, which doesn't make a lot of sense when there is absolutely zero increase in performance. Why make the system more complicated for no gain?

If you're having arcing issues around the plug boots, you can replace them without replacing the entire coil rail. They're about $2 each. So that's not an excuse to do away with the rail.

The Dodge coil pack is $30-$40 cheaper than the XJ coil rail. But you don't really save that much money, because you also have to buy plug wires and parts to make your bracket. If the coil rail were something that you replaced often, it might make it worth it. But my coil pack was still sparking fine at 160K miles when I did my engine swap. I went ahead and replaced it with the new motor, but I kept the old one around as a backup just in case I ever have spark problems. If there's nothing wrong with your existing pack, there's no reason to throw out a $70 part just to replace it with a $30 part. You haven't saved any money.

Maybe someone has another legitimate reason to do this, but the only one I can think of is that you decide to replace your 0331 head with an 0630. Then it might be easier and cleaner to install the Dodge coil pack rather than try to rig up a bracket to hold your coil rail on the head that wasn't designed for it. Personally I would rather go with an aftermarket 0331 head made for the 2000 so as not to have to bother with any extra brackets or potential exhaust issues, but it might make sense if you could get an 0630 for cheap or free.

Any other benefits people claim are probably going to just be smoke.
