What is Inverter Service? How will it improve performance? on 2004 Toyota Prius

What does the Inverter do?

1 answer
It won't improve performance. It will increase the longevity of your car. The coolant used on the inverter is only effective for 2~3 years, and needs to be flushed. http://artsautomotive.com/publications/7-hybrid/116-prius-30k-service/
