Unless you are extremely modded (i.e. forced induction, nitrous, etc) just use the Copper Champions. They are cheap, easy to get, and you have to change your plugs every 30k, so why bother with expensive plugs?

What is your definition of "easy". Obviously the Bosch IR Fusions are the "best" because they cost the most............unless of course you like something else! LOL :D

This is kind of like what is the best oil or best tire. Everyone will have a bias, but you can't go wrong with OEM Champions, but I have not had any problems with the Bosch IR Fusions.

I use the NGKs and I'm pretty close to bone stock. No difference over the old champions to my feel.

Just playing devils advocate here but..............I've seen a lot of posts like that and often wonder when the Hemi was being designed, were the NGK 5306's available back then to use?

Also, with costings being one of the manufacturers/bean counters main worries, would they have used them anyway?

I highly doubt that they would have used them.;)

Just a couple of points, as I've been using these NGK's for well over 48,000 miles without a problem using dual fuel as well.

Chrysler has always used champion plugs for the most part. I know in some cases ngk is used, but its not often. Why? I would guess because the champs are cheep, but it doesn't matter as your ignition system is designed around them...so they are without a doubt the best choice. FWIW they are one of the few companies that dont use ceramic pads either!

I just changed mine on Saturday and went with the stock champions, cost me 30 bucks and about 2 hours of my time. Like I have said before in my opinion I see no benefit in spending 5+ for a spark plug that will be changed out in 30k.
