i dont know much of it so what are the pros and cons?

 

pros-cleans up look of throttle body a fair amount, more HP by removing secondary throttle plates and removing coolant

cons-removes cold start thermowax (which i believe dosnt really do anything useful, or at least if you dont live in Alaska or somewhere)

I say go for it!

 

Another pro - Quicker throttle response

Another Con - less smooth on-off throttle transitions.
