What is this??

Hi I found a pic of the same car as mine but it has this red thing across the suspension tops under the bonnet.

What is it?
How much do they cost?
What does it do?
Worth getting one on mine?

Thanks

Can it do any harm at all ?
Its my everyday car but I like to rag it round country roads at the weekend

Ive just been looking on ebay and it says youve got to remove the standard air box and get a induction type filter. The one in the pic up top is in the wrong place, will just be sucking in warm air loosing power
