What kind of spark plugs go in a 2003 Dodge Dakota with the 3.9 litre V6?

Answer 1

go with cheap champions, it came on the vehicle and a spark is a spark.

Answer 2

As you can see everyone has advice and opinions. Your truck originally came with Champion Spark Plugs in it. Look at the whit sticker under the hood and it will tell you what spark plugs to put in there. It will probably say RC12LC4 which is a Champion plug number. Autolite 3923 or 3924 will work fine too. It should also tell you that the plug gap should be .035".
If you do a lot of highway driving I would run it up to .040". A little bigger gap won't hurt on the highway.

Buying "Super Platinum Plus Titanium Megastupid fancy name bells and whistles burns in oil B.S." plugs is not only a waste of money, it is a waste of time!
If you want to wait a while before having to change the plugs again, use platinum plugs, either Autolite (prefix AP or APP) or the Champion equivalents.

Stay away from Bosch!! It wasn't made in Europe! Bosch's work great in VW's, Mercedes, and BMW's. I have taken may sets of Bosch plugs out of crappy running American engines, put the factory recommended plug back in (NOT BOSCH) and the cars ran fine. I even worked at a Bosch "Certified" Service Center and the owner even agreed that they are junk when it comes to American cars.
I also hate Champion plugs, I think they suck but, I found after experimenting with my wife's Neon, that they worked the best and lasted the longest for that particular engine. I tried a set of everything you can imagine out there (yes everything! Hey, I worked in a parts store, why not!), and I ended up using the ones that I hate the most, but they work. Just proves that you should use what the factory recommends when all else fails. I even ordered them from the dealer since Advance (where I worked) did not carry them at the time! $$$!!

In you truck (I have had a few Dak's too) you would be fine with the Autolites or Champions. I have run both of them brands and saw no real difference.
Don't forget the wires. Buy the "middle of the road" set in regaurds to cost, those cheapie sets you get from AZ and ADV are just that, cheap. The Autolite wires at Advance come with a lifetime warranty, cost a little more but work good, besides if you keep the reciept you can go back every year like I do, and Defect Exchange them for a new set for free. Can't argue with that as long as you don't mind changing them! Those overpriced 11mm silicone racing wires are not only a waste of cash but uneccessary.

Answer 3

go to your local parts store an they will tell you what it is you need, it all depends on the Brand you prefer, all brands have different stock numbers, I see people recommend champion plugs, personally I think they are junk, never have had any luck with them, I prefer AC delco or auto lite.

Answer 4

Drop in Champion Platnums or Autolite Platnums. nothing fancy.

Answer 5

go to Auto Zone or any parts store around your neighbor hood they will tell you what kind the plugs you need for your car just tell them what make and model and what size of the engine.

Answer 6

hey there go to your local parts store and tell them the motor size of your truck year and everything and they have the listings on there computer files and its that easy and you can buy your plugs at the same time too

Answer 7

Personally, I would use Autolites gapped at 0.040 (spec). I would also use Platinum or double Platinum unless you plan to change them about every 30K miles.

Answer 8

Resistor Type RC12LC4

Answer 9

I have the autolite 3923 in mine.

Answer 10

I would use Bosh.
