Most of these items are recommended life expectancy of 100k miles, but alot depends on age, milage,usage, and so on. At ten years old, I'd replace them, regardless of milage if they've never been replaced.
I'll be changing my '97s for the first time this coming spring, when I fugure to have close to 50k miles.

Let's hear from the rest.......

Change the Cap and Rotor Every 30,000 miles to keep everything healthy on your truck. Better performance, fuel milage, quicker starts.... also change your fuel filter with it..............
