I hit 32k and I need to get these replaced. Most say stay with a champion plug. Anyone with some personal experience w/ the HEMI?

 

Yeah.................... don't want to steal the thread but I'd like to know for my 03 1500 as well?

 

I've been working my @$$ off to get new plugs for my 04 1500. I settled on NGK G-Powers. I called Dodge and they gave me the typical "you should only use Champion plugs" crap. I talked to a bunch of guys on here, and did some research on other posts, and Mill500, who I really respect, said people have done fine with NGK's. I heard since the HEMI runs at a higher temp, that copper plugs should be avoided. However, the Champions are copper plugs. No figure. If anyone else can clear this up, I'd appreciate it. Until then I'm gonna install my NGK's and let you all know. Supposedly, if the HEMI gets non-Champions, it will spit up and throw lights at you. We will see.

P.S. Dodge also said you shouldn't have to replace the wires or coil packs unless they actually go bad. First time I ever heard a shop to tell me to NOT spend money.

 

I asked the same thing and i put the NGK V-Power Spark Plugs in took about 2-3hrs and new 8.2 Taylor Thunder Volt Wires well I dont know why but now all I get is 9.8 mpg Highway doing about 65mph befor with the champions and the stock wiers I was getting about 14.8 to 16.5 mpg so Im thinking about going back hope I helped

 

Not to hijack the thread or anything, but do you think its maybe the wires or the plugs? Gonna try and trouble shoot?

 

I went with Iridiums and the 8.2mm Taylor Shorty's...big difference in throttle response...

 

Any codes thrown, or poor mileage with the NGK Iridiums?

 

...no codes whatsoever, truck runs really strong, i wish I could tell about mileage but I drive my truck pretty hard and get on it often... I have SC, modified CAI, Flow 50's, powerwire and shorty's (which makes both spark plugs in a cylinder fire at the same time as opposed to one on the opposite bank)
