If so, would what would you charge to do mine? I live in the Dallas area, with an 2007 right at 120k. I know it's an easy process for those with the right tools, skills, and time. Unfortunately I don't really have any of those, and I would rather pay a fair price to a fellow Prius owner than a hefty rate to a local shop. Shoot me what you think is fair and we'll take it from there? Be sure to include roughly where you live, and your spark plug resume. Thanks!
