Okay I tried to replace the mass air flow system on my son's 04 with a KN air flow system. however when the it is installed it make a horrible dry grinding sound every time you start it and then when are just driving down the street going about 35MPH in 4th gear it starts to make that sound again.
Any Ideas what it might be? To much airflow and then the mass air meter shuts it down?
Once we go back the the stock air flow system everything is fine....
