I think its that colder air allows more air/fuel to fit in the cylinder, producing more power....(others can correct me if I'm not spot on...)

Cold air is denser than warm air, so that should mean there is more volume of air entering the combustion chamber on each intake stroke, and more air means more power.

However, I also notice the firmer(due to cold) dash pieces vibrate/rattle more in the winter...

No rattles in the summer, plenty in the winter....

I noticed that today too. lots of rattles

couldn't find the source.

then again, maybe I haven't heard it before b/c I blast music all the time.

Its rather simple chemistry. The colder something gets the more dense it is.

So when its colder out and the air is more dense, you get more O2 then you would with warmer air. the trade off is definitely your tires grip.

Its kinda like N2O, the chemistry behind that, you burn more MOL of gas per MOL of oxygen.
