How many miles are the stock plugs good for, what are some good replacment plugs (performance and long life) and most importantly what is the proper amount of torque (in foot/pounds) to tighten the plugs to when installing them.

GM claims the stock AC Delco spark plugs are good for at least 100K miles, however, there is no guarantee they will last that long. The best replacement spark plugs are AC Delco Platinum or Iridium made for your specific engine. Spark plug torque is 20 ft-lbs.
