Need help/tips on removing the throttle body (Megane RS250).

Hi guys,
Planning to pull the throttle body out on my Megane 3 RS for a clean. Access looks tight.
Quick questions:

• Do I need to remove the battery, battery tray, and ECU to get enough access?
• Do I need to take off the whole intake track / airbox, or just the main induction pipe?

Any quick tips or shortcuts to make the job easier?
Cheers!
