Did this come with the smoke and mirros or do you have to provide those, too?
Looks like these faux 'cold air intakes' are the coming trend. Doesn't *anybody* buy faux carbon fiber strut bars any more?
Did you actually *believe* that sales pitch characterizing your stock air intake as "restrictive"? Do you have any idea where the greatest restrictions in a BMW intake tract are? [Hint: it's not the air intake box.] Do you really think a hunk of conductive *aluminum* will be any cooler than a piece of plastic? [Another hint: which one do they make cookware out of?] Finally, how do you think the air where this thing mounts will be any cooler than that right behind the headlight (or wherever BMW is getting it these days)? Making up a big ol' plastic molding for getting air from wherever they want it is a simple matter for the designers of a $40,000 car. Why would you think somebody selling this stuff in the aftermarket is any better at it?
Read the benefits statement carefully: *Designed* to improve horsepower and throttle response up to 10%. Do you see any indication that they actually *achieved* this design goal? Can you even tell what the goal *is*? [Next hint: they never said *horsepower* would increase 10%]
I hate to be the one to tell you this, but your 'upgrade' will almost certainly be as beneficial as the throttle on a Harley Davidson: it's a *Volume Control*!
