so i went to change my sparkplugs tonight fo one all i can say is wow the boots are such a pain to get off, but the weird thing that i noticed is that the Plugs where ACDELCO and also had YELLOW dots on the top of them could this mean that these are what came with the car when it first came out ? it's a 97 gtp you would think that these plugs would have had been changed at sometime but i have never seen plugs that had yellow dots on the top of them. So i am just curious

I cant say that I have either, so it will be interesting to see what is discovered about that.

could it be some paint put on as a tamper seal?

i would say yes to that but these are perfect dots i will post a pic of these in the morning, maybe someone on here will know, i would just think that it would be crazy if these where plugs from 1997 and the previous owner never once had them changed.
