I've been meaning to ask this question for a while now, but kept forgetting because it's not a huge deal. Shortly after I got my car, I noticed a couple things that made me think my car might have some kind of 'Cold Climate Package' installed, but I'm not sure if it's just me. Behind my grill (the two lower honeycomb grills) I have black styrofoam looking pieces that are plugging the grill. You can't tell it's even there unless you're up close. Is this normal on all '03+'s? Also, around my battery is a blanket looking thing with a plug & wire harness on the back of it? I thought this might be some kind of battery warmer, but I could be wrong. Any ideas? Thanks!
Here's a pic of the lower section of the grill that's plugged:
