Please educate me on Throttle bodies

So I have a eurocharged 172mm pulley (with cooling mods) and Kleeman headers coming in the mail and was wondering about upgrading my throttle body.

I assume a 82 mm throttle body will help, but in what way?

Does it just help with more airflow to go more aggressive with the tune?

Where can I guy one of these for my CLS55?

Are these upgraded TB's plug and play (OEM fit)?

Engine is like an air pump. More air you get in and out the more power you make. Upgrading your tb allows more air in and therefore more power. I would get tuned after
