The service being recommended to you is called a Fuel Induction service. This is when cleaner is introduced into the engine through the air intake (vacuum) and cleans various fuel system and engine components that way.

Unless you are having a specific engine performance issue, I would say that this is a "performance upgrade" service, not a "required maintenance" service. You may yield benefits to having this service done, such as improving performance and fuel enconomy incrementally. However, if you are not experiencing any issues driving or running your Saturn, you probably don't "need" to have the work done. It is often recommended by technicians during routing maintenance on your car, often based on age and mileage more than verifying any specific issues.

As a side note, Fuel Induction service does carry some marginal risk, as introducing the cleaner into your intake can foul out or damage oxygen sensors or catalytic converters...all on unusual, rare occasions. But I have witnessed it before...and it is not a good situation to be in. Especially if you are not experiencing a specific symptom that you are trying to correct.

My personal opinion is that this is on the lower end of the spectrum of things I would absolutely do to my car for maintenance. Services like brake fluid exchange, transmission fluid service, filter replacements certainly are needed more urgently for regular maintenance.

Hope this helps.
