Either by the premade coil head you use - eg nautilus is tighter than subtank - or RBAs which come with airflow controls - ed insider is, I think, tighter than exocet, and both have airflow rings - and some people use kayfun (I think?) airflow restrictors too.
I see, must get me a Billet Box and join the fold!
Thanks @cindy99
