Yes, are you referring to a RBA or a bottom feed clearomizer? It will make a difference as far as the response you get.
An RBA is a rebuildable atomizer, you build the coil and rewick it yourself. They come in top feed and bottom feed.
A clearomizer also comes in top and bottom feed, some you can rebuild some you may only be able to buy premade coils.
Let us know which you are referring too.
