I am using the trp plts. They work great. gap at .038. They might be 4.00 a piece but I put them in and have not had any problems, starts fast runs even better. Tried just about all plugs, so far these have worked the best.

I used them from 1997-1999 and then switched to the Autolites. I'll never go back to SplitFires. (I've been using SplitFires on my vehicles since 1989 and they do work...but the Autolites gave the same performance without the hit to the old pocketbook.)

you don't need to change from stock plugs. if you changed your fuel or compression, you might need a different heat range plug. just by cleaning your carbon build up from your throttle body to combustion chamber will improve your throttle response, idle, and fuel econ.
p.s. slit fires are stupid, you can not split a spark.

You can change your plugs to either the factory replacement or the autolite 3923 (or equivalent). Performance wise, Dodge has really "bit the big one" on the detonation problem. I've heard anything from "that's normal" to "well the other ones don't do that" to "must be those modifications you've got installed". (Hint: PCM program, hot spots on the bowls - poor QC at Chrysler, and a plethora of other problems have driven DC to retard the PCM program by up to 4 degrees...seriously hindering performance. But DAMN does that program work great on blower applications!)
Cleaning the carbon deposits is great if you do it on a regular basis...but that also requires removing the TB to properly clean all the ports. Throttle response can be affected by a dirty TB...agreed. (Now why the HUGE variance on TPS sensors...funny how they respond much more "crisp" at .7v.) ;)
You're right, you can't "split" a spark, but you CAN build a better plug. (Chrysler Tech...so have you seen the problems caused by the Mopar Performance replacement spark plugs? Pretty nasty when the MIL trips due to those plugs mis-firing.)

Hello friends, bernd called it right. He's using AUtolite Copper Core ignition engineered sparkplugs for his dakota. He knows what works and what doesn't and thousands like him have made the switch.
Don't delay! Try a set of Autolite copper core resistor sparkplugs today. Feel the pep and the urge your motor has once you install Autolite sparkplugs.
Be right, use Autolite!

I tried Splitfire plugs 6 years ago back in high school on an old snowmobile setup for drag racing. I built the motor and decided to try the plugs. The plugs did nothing but cuase loud backfires and ruin my jetting. ANY PLUGS THAT SCREW UP A SLED THAT BAD WILL NEVER RUN IN MY TRUCK!

Ding ding!! We have a winner!
Yes folks thats correct. Extra prongs do nothing but get hot and help induce detonation. A spark will arc the shortest possible gap. Thus the picture that Split Fire uses of the spark shooting up between the prongs in nonsence. It will arc to one prong and one prong only.
+4's are a complete joke! 3 prongs are along for the ride on every stroke. Save some weight and go back to single prong copper core spark plugs.
In any sort of a forced induction engine this will be even more pronounced. If you can run Split Fires and/or +4's and don't get detonation, I'll bet if you hook up a scanner to it, you'll find that the SBEC has pulled your timing back and you are actually hurting performance.

Uhhhh....Autolites are not Ford products. ;)
BigBlue: Yes, those are the ones.
Funny thing that isn't mentioned in this thread...all of those pictures, and most "demo" boxes (MSD, Jacobs, Borscht, SplitFire are the main ones), use the plug "spark energy" test in a non-pressurized situation. I'd like to see them take those pictures inside a live combustion chamber (under pressure).

Hmmm...you did add the "hehe" part, so can I assume you are joking??
++++++
"Are the Autolite 3923's the copper core you of which you speak???"
Yes, and Champion and AC Delco are also copper core. I am pretty sure that NGK and Bosch also have copper core versions (look at their "base" model).
Heck even unobtainium core plugs with one prong would be an improvement over split fires and +4's.
Amazing thing isn't it...the cheapest plugs use the best possible conductor of electricity.
A noted Chrysler turbomotor engineer/expert used to always say: "stock is trick." And while it has its limits, in many situations, it is VERY true.

back in late 60's and early 70s when i was a master mech. for chrysler dealership . customers would bring there cars in that they tried to tune-up. most of the problems we found was the use of AC plugs instead of mopar (champion) plugs. But that was the good old days. 318-340-360-413-426-440 and the 2 slants ..173-225 if i remember right. I'd like to see gen0 back again. have a great day.

Ford had to sell the sparkplugs division to Allied SIgnal in 1973 due to antitrust issues.
