I was wondering for one if i can remove it and two what do i need and how to do it ?

 

remove it perminently? Or just remove it to replace it..

If you are asking if its okay to remove it perminently, then I would do a little research on how a PCV system works, and then decide if having it around is really that offensive.

 

Do people replace it all or do they just keep it as it is ? Im just wondering if people do anything with it in general i guess.
