Generally, the intake system can be regarded as the most important part of NVH characteristics of a vehicle. In this study, the general approach was introduced to improve the characteristics of the intake system which had a great deal of vibration level in idling. The essential vibration characteristics of the intake system was identified by spectral analysis and modal test. Several countermeasures to improve the characteristics were considered by FE analysis. Finally among those countermeasures, the best one was selected and its effect was proved in the vehicle.<br/>
