Porting an intake manifold essentially helps increase airflow into the engine. Improved airflow equates to more horsepower and helps the engine feel more responsive at the throttle. A standard intake ...

In this study, the effect of intake manifold geometry on cylinder-to-cylinder variation was investigated considering the volumetric efficiency, early tumble development, turbulent kinetic energy, and ...
