Honestly, yes. But I have a hard time getting past my roots, which was changing plugs and points twice a year.:duh: If your truck is running good and the mileage hasn't dropped any, there really isn't any reason to change before the 100k and even then. Unless you have the time, money, and just want to be pro-active about maintenance.
