They have done a lot of tests on those 2, 3, & 4 prong plugs & most have shown that they don't give any better spark. They just cost a lot more. The best thing to do is just use whatever brand the OEM recomends & buy the better quality of them.

I actually have read that by using the 4 prong plugs have actually caused damage in some vehicles

Gm platinums are some of the best going and easy make 100K miles plus.
Check your manual and whatever GM reccomends do it. I'm a pilot and the two prong plugs are good because when one prong wears down the other cintinues the spark.
