Okay so I read through a guide on how to change the stock TB to a 74mm TB, I am interested in doing so, but will I still be able to hook a needswings CAI? I have no modification experience, I have only changed out stock parts for new ones.

Also what's the size of the original one, and how did the 74mm come about? I mean how do I search or find out information when I want to try something new. How did you guys find out all the different part that'll fit from one car to another?
