The Red Warriors went behind at the Tuanku Abdul Rahman Stadium in the 14th minute when Firdaus Azizul fired an emphatic left-footed effort past Khairul Fahmi Che Mat.
However, they equalised two minutes after the break when Azlan Ismail fired home from close range after an Indra Putra Mahayuddin effort was cleared off the line, before Mohammed Ghaddar raced clean through down the right and fired them in front in the 63rd minute.
Ghaddar then turned provider five minutes later when he broke free down the left and slid in a ball for Indra Putra to tap home, although Kelantan were made to endure a nervy ending to the match when Shukor Adan headed home a corner from S. Kunanlan in the 86th minute.
