Platinums are a horrible plug for these cars.
09-28-2014
How come?
09-28-2014
The waste spark ignition on these cars burn them up prematurely

So how long would you exspect to last,I've heard pros and con's on platinum and iridiums and definitely don't put copper
09-28-2014
you car came with iridium plugs, its what belongs in the engine.
copper are cheaper, dont last as long, but work even better.
09-28-2014
Copper > iridium > platinum
If you're keeping stock then use iridium.

Oh ok,somebody had the ac delco double platinums in the se and gtp
09-28-2014
I guess it will be ok until next change,so iridiums came from factory?
09-28-2014
well that was wrong. ( someone f ed up along the way) i bet it runs better with the right plugs in there.
09-28-2014
I can see a big improvement now with the new ones in,idles smoother,both had ac delco 41-921 in them
09-28-2014
what happens is most who put plats in find out they have misfires in a short amount of time, who knows, maybe your car likes em lol
there are guys who run and swear by them, but why pay so much extra for plugs?
09-28-2014
These were 3.89 a piece,so I guess with time we will see,anything will have to be better than these
09-28-2014
Some where worse
