.050 is the spark plug gap if you have the 3.8L engine. Hope this helped and best wishes.
Do not use old plugs to find your gap. The reason you are replacing the plugs is because the material that the arc hits slowly corrodes and disappears. if you keep doing this you will soon be having issues and poor performance. DO NOT USE OLD PLUGS TO GET YOUR GAP!
If is a 3.3 .050 gap
