I am looking for a recommendations on which spark plug to use on a EJ22T with DOHC heads.
Are people with the DOHC heads just running the EJ22T recomended NGK plugs?

I'd run either the stock EJ22/EJ22T plug BKR6E-11 or a regular BKR6E at 0.030" gap like an EJ205 has. All the turbo Subaru EJ engines basicaly used the same plug. Some NA EJ25s were a temp range hotter though. Late models run a platinum plug, but I recomend a regular v-power since you're moding, replacing plugs is inevitable.

Yes NGK BKR6E or if you want to run one step colder BKR7E.
However, sparkplugs in a DOHC are a pain to change. So if you dont want to do it often you may consider the PFR6G-11 which is OE double platnium.
