I'm not sure if it's the cold air or the fact that I'm now at around 4,200 km's (2,800 miles), but I thought I noticed a bit deeper exhaust note and a smudge more umph when I stomp it. I've noticed it more in the last two weeks.
Perhaps the cold air is doing it? It's almost at freezing in the mornings here already.
: With my 1.9 I noticed quite a bit of difference in the performance between summer and winter. With the denser colder air the Z3 seems to pick you some extra power (at least my 1.9 did). I assume the colder, denser air is like adding a bigger air intake on your car, except this time mother nature is picking up the tab.
: Curious if I will see the same type of performance gain for the M, and I would be interested to hear what other 1.9, 2.3, 2.8 and 3.2 owners think about mother natures free upgrade.
