Air Scoops - Functional or Cosmetic?

I know this question will probably get laughed right off the forums, but I think it's worth asking...

With how much talk or air scoops goes on I am wondering if it is simply a cosmetic/mental thing, or if it truly does boost engine performance by funneling more air into the intake. I'm not looking for oodles of gain, but is there any functional benefit to scoops, or is it simply cosmetic?

Thanks!

At speeds only legal on the Autobahn - possibly. In 'normal driving' - unlikely.

I figure that i like the way they look and any power increase is just a bonus

Functional above 70 mph for sure. Better throttle response mainly.

I wouldn't go so far as to say it has like 20 more hp. maybe +2 hp above 80.

Cosmetic in that people realize it probably isn't a stock BMW anymore.

I don't think that scoops produce any more power than your car can already make. It does help fresher, ambient temperature air make its way to the intake. I have them primarily for traffic where otherwise, hot air from my radiator gets sucked up instead of fresh air which is cooler as well.

I'll start by LOL! There's a huge thread about it if I remember.. But seriously I have them installed too lol.. For $30/$40 used/new why not right? It's just another mod to add to the list. =)

I would argue that air scoops are neither functional nor cosmetic.

air scoops = bug eaters

M3 guys gained 2-3hp at 80mph+. That's the only dyno I've seen...this was back in the day

I've got'em. Only downside I see is driving in the rain

At least the Cyba scoops have slots in to redirect the rainwater away from the airstream...

I wouldn't bother with them, esp with all the rain and bug we have down here.

They look gross IMO. Not to mention probably nothing in overall performance. They should be shaped more elegantly than some fat looking rectangles. No thanks...

Do you need little air scoops underneath your nostrils to help you breath?

Intake air scoops do not add anything to performance, because engine air intake is negative pressure under load, like a vacuum. Engine will suck the air it needs. Force feeding it into the engine will not help. You are only feeding dirt, bugs, and water into the intake.

If these cheap pieces of plastic actually helped with anything, BMW would have installed them on the car at the factory. Don't be idiots, remove these things off your car.

8 month old thread brought back to life because you seem quite upset about this?

Bull shit! I had more bugs in my stock airbox before I did scoops and had 1 bee in my aFe CAI. And I live next to cattle and horse ranches FYI where my commute takes me through the grazing fields.

Hmmm...so why did normally aspirated Formula 1 cars have huge air scoops then?

I love cows but they produce methane. The bugs are flying away from it and your engine is exposed to additional heat.
