Air flow behaviour plays an important role in order to provide better air fuel mixture inside the intake manifold for port fuel injection (PFI) system before it is drawn to the combustion chamber. This paper presents a computational fluid dynamics study that investigates the air flow behaviour inside a different intake manifold angles. This study is a continuation from the author’s previous studies that have been conducted by experiment and simulation study using a different simulation tool (GT-POWER). Six angles of intake manifold have been investigated using CFX simulation tool which are 30°, 60°, 90°, 120°, 150°, and 180°. From the study, results indicated 180° as the best option for intake manifold angle due to better air flow behaviour inside the intake manifold. This show an agreement to the previous submitted results that was done by using GT-POWER.
