my dad has 150k miles + on his 99 and still gets 30+mpg. Really the prices for these platinum plugs are not that bad, I was expecting $10+ a pop but they are under $3-5 at the Rock.

My car drives awesome and it's even better after changing the coolant? = I don't want to ruin what I got. Maybe next year for new plugs.

My 1966 Dodge Charger just had it's plugs changed and I noticed a huge improvement. Plugs aren't under a $1 anymore, but they are made better and have more copper. = It's worth the change.

I remember when the split electrode splitfire spark plugs came out (1990?)
and I thought those plugs were not worth the extra $$$$.
