With all the talk about the AFM / MAF...

I thought I'd ask a question that's been bothering me for sometime.
On my '89 S2 race car there are a pair of radiator hoses that go into the back side of the AFM (?)/ throttle body.
The only thing I can think of as to why Porsche would do something like this is to help get the car warm on cold days.
However, on a race car I can't imagine any benefits and in fact I can see that by warming the incomming air it would actually be detremental to making the max HP possible.
A friend with the exact car has disconnected his and I'm wondering if this is beneficial (he is faster than me
)
Here's a pic with my son showing the hoses in question.

that is mainly for cars in very cold climates- for a race car- or a street car that doesnt see cold weather often- just put a jumper line between them and connect the hoses w/o the throttle body. Seen it done no biggie.
