Yes spark plug wires can last 100,000 miles, but i would do an annual inspection on over around five years of age , check for wires being brittle or if an oil leak is near a wire its not good either, check the boots to see if they are still in good shape check for cracks or swelling, oil soaked ,and make sure they are a good distance from the manifold exhaust or headers, if you want to try to make them last you can get more than 100,000 moles out of them.
