It's not that, if you know how intakes make power then you can respect what the guys saying to use stock are talking about. If you've got engine management, get one. You can tune for it to safely make your power that they advertise.
People have this misconception that they throw XXX's intake on and boom, more power, when in all actuality, it's not quite like that. In some cases the ECU's going to flip out and pull timing, then, there went all of the "power" that you just made.
Sorry if I'm coming off like a ####, no offense.
My car is well, it's like 10 lbs of shit in a 5 lb bag...
