I believe the spark plugs in this car get changes at tune-up time which is supposed to be 100K miles. Im at 53K and change and I have never even pulled a spark plug in this thing, lol.

At 50k my plugs looked ready for retirement. You may want to check out one of them!

Whatever the book says, cut the figure in half. With mods you may be running a non-standard air:fuel ratio potentially shortening the life of the plugs.
