In order to change a manufacturing process, the plastic air intake manifold had to be modified with the runner length and diameter because of package problems. The original process is "Lost-Core" and the new one is "Vibration-Welding". The reverse engineering has been done through scanning the original intakemanifold. And scatter bands of the design parameters were picked up. The computation fluid dynamics (CFD) and the onedimensional engine performance simulation are showed in this paper. In addition this study would like to show how to put an output from an analysis work into a design process.
