The Porcupine Warriors threw away a lead to concede twice in the space of 10minutes.
Kwame Opoku gave Kotoko the lead after 69minutes with a calm finish having received a pass from Latif Anabila.
Substitute El Amin Amoura drew Setif level before Abdul Fedouhli added another to give the visitors the lead.
