Iridium plugs

[transient]

Howdy,
Now that gas is twice the price what it was when I bought this 96 ranger, would I get much benefit by using a better spark plug, cause Iam at the 100,000 mile mark? Would this cause any probs for me? Iam plan on taking it in to a shop thatll install them cause they said itll take a good 2 hours to change em, I cant imagne how long it would take me to do them, thanks.

new plugs will help fuel milage only if old ones are bad. the difference between stock and high performance plugs isn't more than 1 mpg better.
