GM V6's are the worst,more so those back 3 wires.[/QUOTE]

Back in the day I had a 92 Lumina with the 3.1 v6. A back plug blew out, what a terrible job! It's good to know about the 30k, mines got 23k

Between $60 and $70 a set at discount outlets, at dealers parts counters about $80.

I was quoted 65.44+ tax for 16 through dealer after haggling and $320 if they do it. It has OEM NGK but OEM champions which were used before 09 are $1.65, can they be used in place of NGK? Any issues with doing it, anything to watch out for?

Just that many say Champions seem to have a higher failure rate than NKG. At $1.65 they could be seconds... but I dunno. Could just be a great deal.

In a Jeep the Champion plugs are a much better plug then the NGK's.

That's not right, most here have had better luck with NKGs on 2011+ motors. NKGs are a better made plug. There is certainly no significant difference between them. Some swear by champions in earlier year and classic hemis, however.

I hate both brands but run Champions in my Jeep but they dicontinued the correct plugs.Never liked NGK,besides there O2 sensors(NTK).


On a side not NGK used to sponser my buddy's drag car,made custom plugs for it and sent him a 10 sets,turned out all 10 sets were flawed.He found out the hard way when one came apart at 8500rpm's with the full 500hp NOS shot going destroying at $60k engine and most of the car.NGK x-rayed the other plugs and found all had micro cracks and most likely would have failed also.The only good thing is they bought him a new engine and new car then he told them to pound sand.He now uses Champion plugs with better luck.

$84 for 16 OEM NKG plugs and two quarts or Mopar NV245 transfer case fluid. Pretty happy compared to the $7 per plug and $21 per quart originally ask by dealer.

The plugs removed had gaps varying between .043 and .045, is this normal for 30k miles?
