I put the copper core 3923's in....should I have put the platinum ones in or are we supposed to use the copper ones?

 

I have read that the plats. suck for our truck. How do you like those 3923's? I'm having a set put in my truck today.

 

the 3923's work really really well...truck idols smoother and also you know it seems to run better in general...and thats why i bought the Copper Core ones cause I remembered something about someone saying that platinum doesn't cooperate with our trucks that well and to get the copper ones...but I had a brain fart for a minute!

 

Just put them in and it runs great. Much smoother idle.

 

the plats are plain out terrible. stick with the 3923 or 3922 and you cant go wrong

 

I read and have been told that champion spark plugs are the best replacement for mopar engines. Maybe that was just from back in the day. How often should the plugs be replaced? I'm at 22,000 miles on my 05 dak with factory plugs

 

I believe the manual says they should be replaced every 30,000 miles....I think most people here have done that, or even earlier.

 

Yeah well i treat mine like the turbo Cars i have had...Change them Every 15,000 along with the Differential's, transmission fluid, coolant, just keeping everything fresh you know! so yeah...but thats me

 

my turbo bird I changed spark plugs at about 10k miles maybe sooner

 

IJust changed the spark plugs with 3923's and I took the truck out for a little spin and now I have the Malfunction Indicator
Lamp on. The truck is a 05 V-8. Is there anything that I could check to see what might be the matter. The truck seems
to run fine, better than before I changed the plugs. The light comes on when I start the truck and it usually goes out but
now it stays on. Any help would be greatly appreciated. Thanks.
