I know there's a similar thread, but I want input on topic for my car. I'm considering adding an Air Intake System to my 2004 325i. Is this a waste or do will it boost performance? Pls share any experiences... Thanks. MEL
No extra hp. If it isnt designed to get cold air you could loose hp at low speeds. You might like the increased engine sound though.
ok, thanks for your reply, always helpful. I'll do more research, ask dealer about it and consider something...
