Following a goalless first half at the Jurong West Stadium which saw the hosts enjoy the better chances, the Warriors were awarded a penalty in the 79th minute when Ismail Yunos was adjudged to have handled the ball inside the area.
Mislav Karoglan stepped up and calmly stroked home what proved to be the winner, leaving Gombak feeling a huge sense of injustice after Wednesday's first leg had also been decided by controversial penalty by Tatsuro Inui, after Nurullah Hussein had been penalised in similar circumstances.
To add insult to injury, the Bulls also had a goal from Jung Hee-bong disallowed after Obadin Aikhena was flagged for offside despite not being involved in the play, although SAFFC also had a header from Karoglan chalked off on the hour mark.
Saturday's victory also means Warriors coach Richard Bok is on track to bow out on a high, after the Singaporean tactician confirmed earlier in the year this would be his last season at the helm of the club.
SAFFC's opponents will be decided on Sunday when Great Eastern-YEO's S.League leaders Tampines Rovers take on Filipino outfit Loyola Meralco Sparks, with the former leading 2-0 on aggregate.
