I was wondering what exactly does a drycharger accomplish? And do all cobalt's come with a cone filter? I do know it is in a unique place and is a wierd shaped air-box... but don't know if I have to buy a cone filter and remove my airbox... any help? Thanks.

The Cobalts (the SS at least) has a cylinder, I think it's the same as the Trailblazer. I don't have a clue about the 2.2 'balts though.

I dont know, I bought one, and I will let you know once its installed. its basically a replacement for the paper filter that comes stock with the car. Its suppose to be a cone filter for the most part just instead of being big and getting smaller as it moves to the tip, its more like a coffee can, and helps reproduce the stock look and airflow and accurately as possible. It allows more airflow tho, and does not use any oil. its also washable and reusable.
