On a 2006 GMC Envoy, the spark plugs are located on the engine's cylinder heads. For the inline-six engine, they can be found on the top of the engine, accessible by removing the engine cover if present. If your Envoy has a V8 engine, the spark plugs are located on either side of the engine block. Always ensure the engine is cool before attempting to access or replace the spark plugs.

Depends on the type of spark plugs. Factory plugs around 70 - 100k depending on the condition of the plugs. I would replace the spark plugs out with some AC Delco iridium plugs they will last you 100k+.
