What is your question?
I have a 96 Buick Riviera, and I need to know how often I should change my spark plugs.

It is recommended to replace the 6 Platinum/Iridium Spark Plugs every 100,000 miles.
100,000 miles ,ay be whats recommended but i would recommend replacing them at 70,000 to 80,000 miles. The plugs can get stuck if you wait until 100,000 miles and be so hard to get them out that it can pull the threads of the cylinder head. I had it happen.
thanks
