VOLVO /BOSCH Powerstage Module

I keep seeing these on ebay...

just wondering. If they do work, is it an easy bolt on?

 

Do you have a link.There is a power stage that is part of the ignition system that is needed for the car to run.If you have a link I want to make sure it isn't that and they are trying to say it is a performance enhancer.

 

Here is the link:

If you have a problem or are wanting a spare in case yours goes bad it isn't a bad deal.But it doesn't do anything but make your car run it is part of the ignition system.
