The best spark plugs?
For saving gas and better acceleration, what are the best spark plugs for the 3.8 v6 engine ?
I have 22,830 miles, too soon to change them?

I changed my plugs at 23k to the NGK Iridium Ix plugs with the Granatelli Spark plug wires and I am very pleased with both. Improved the idle quality and throttle response a lot.

I suggest you pull them now, even if it's just to put anti-seize on them.

I replaced mine at 25k with oem champion platinums. The gap on the plugs were double what they should have been when I changed them. I can't imagine waiting until 100k miles to replace.
