i just put my injen intake and its so loud that it rattles my drivers door at 6k-7k (AT btw) is there anything i can do to the intake or my door to stop that Also threw my check engine light anybody know what that could be?

 

most likely the door handle i had a similar problem. i would use some sound foam.

 

didnt you already start another thread wiht this same probleM? Like i had said before... DYNAMAT stops vibration therefore stopping the rattle
