My old AC Delco spark plugs showed some usage at 50,000 miles. Mechanic said they could have gone the full 100,000 miles. However, I felt a tune up at 50,000 with the AC Delco spark plugs with Iridium would only improve my gas mileage and provide a better performaning vehicle. Tune up at 50,000 may have been overkill, but the ride is a smooth one.

Good vid on Youtube for replacing trailblazer plugs. back one was a little tricky but got them done in 30-40 minutes. Mechanic wanted to charge me 2 hours labor. Definately a DIY job.
