I run Autolite 3923 in my 05 V6, no issues, helped smooth the idle some aswell

 

I highly recommend NGK V-Power plugs. OEM champions are decent as well.

 

so i got a question... ive saw if you get the spark plugs gapped at .35 rather than .40 it makes the engines run better and stops some of that vibration at idle or park

 

?????

 

I have never heard of that before, but you can try it out if you like. Worst case scenario, you regap the plugs back to recommended.

 

Jason, you obviously don't work in risk management . . . LOL

Worst-case scenario is that when re-installing after the second re-gap you cross-thread one of the rear plugs, screw up the threads, have to drill out the hole, tap and find the right thread-repair kit and install it.

I could go on, but done correctly, you are right!

 

so are you sayin if i install .35 it will run smoother??

 

Haha. You got me there. OK, assuming the removal process and reinstall processes go smoothly, what I stated was true.

 

Just installed some NGK Iridiums (9441) today in my V6 07 Dakota. I have no idea if the spark plugs have ever been charged but the truck just hit 60,000 miles, and the spark plugs I replaced were NGK-R's. They looked pretty good when I took them out, so i'm assuming they might not be the originals. Anyways, what a difference! I noticed that the truck is less sluggish and am glad I did it. For me, the hardest plug to get to was the the on the passenger's side, closest to the firewall. It was right there with the transmission oil dip stick and I was worried I would strip the threads because of the angle but I just took my time.
