Im looking to tune up my 3.9L, and hopefully get a little more power out of her.
Any one running this setup, or any other "better" suggestions?

Here's what i was thinking...

(DIST. CAP, ROTOR AND WIRES)

(COIL AND ADAPTER HARNESS)

I'm looking for help with this also; I was hoping that someone "in the know" would have gotten back to you by now.

I don't know what I'm going to do as far as either geting a new cap or go with a hotter distributor setup.

The wires I'm thinking about running:
Bosch 09713 Premium Spark Plug Wire Set. Seems ya can't go wrong with Bosch - from what I read.

Spark Plugs....
I WAS looking into getting the E3.48 spark plugs - the 3-pronged ground strap (to me) sounded like it would provide a really efficient ignition but after reading-through a bunch of different Dakota (3.9L V6 Magnum specific) forums, it seemed that the E3’s are considered a joke. It dawned on me that you never hear about those Rapid-fire spark plugs from the 1990’s either. I decided to write them off…for now.
Seems as though ya can’t better the standard/typical spark plug design(?).

Looks like the most favorable plugs (in order of most popular):
Autolite 3923 (as opposed to the recommended 5224): Very recommended, performance-enhancing for Magnum engines, smoothes-out idle.
Bosch Platinum 4: Good performance, not popular for Magnum engines, allegedly improves MPG.
NGK 7252 FR5-1 V-Power: I read a lot of people saying that they like’em but nothing to backup their statements. Otherwise, they tend to ping a bit per my reading.

I’m personally going with the Autolite 3923; looks to be the best fit for me.

Anyways, hope this is helpful and good luck with your project!
