I put in new NAPA max performance plug wires and iridium plugs, and noticed a difference in performance but not in mpg. However, a week ago I moved to premium gas and noticed an extra 3.6 in mpg.
I have a turbo lite with auto tranny. Today I refilled with mid-grade and will check it over the weekend.
And what is all this talk about lousy factory brakes?
I have 35K miles, just had my brakes checked and still have more than 50% remaining.
However, my battery was replaced under warranty today.
The wires, plugs, radio and battery have been the only weak points I've experienced thus far.
