Might indeed make a different noise on an engine but if it did anything more than that, I'd be surprised and they might be able to write something factual about it to back it up.
Neither description seems to be based on any fact, but the same goes for any aftermarket filter / induction kit. Any power increase would be completely un-noticeable to the driver and the only noticeable difference would be the sound. For that reason I cannot see what makes the bmc one worth considerably more than the other one, especially as the BMC one seems to have more BS in the advert than the cheap one, here is a small sample;
"Finally, dynamic overboosting, greater airflow, higher pressure and colder air are the elements assuring a considerable increase in engine performance in power and torque."
They won't be wrenching £200 from my pocket based on that!!
