Tune a delete stament

Hi guys

i want to tune a delete with select condition statement

this is the condition

select *

from baan.tfxinh115377

where t$koor = 0 and t$ityp = 3 and t$attr = 98;

and they are around 16M rows (16581349)

Do you recommend this statement or there is some way to improve it?

delete from baan.tfxinh115377

where exists

(select * from baan.tfxinh115377

where t$koor = 0 and t$ityp = 3 and t$attr = 98);
