Airbox - What gives?
Well, the guy who owned my 325i (1989) had a cone filter installed. I changed it back today, to the stock airbox. It now seems that whenever I try accelerate, the engine doesnt get enough air. When I stand over the engine, and rev the it, it sounds as if there is an instant vacuum and then it breathes properly again. I dont have the acceleration or power because of this.
Do I have to change anything on the airbox or the airflow meter? If so - How?
