What mods have y'all put on your car to help it heat up in the winter?

And what mods keep it cool in the summer?
I've found my vehicles have all continued to get better fuel economy the hotter they got. E.g. MPG numbers are better on a 95F day, than on an 80F day, even.

In winter, running a small block heater for 1-2 hours before leaving is cost effective.

It's easy to do a quickly removable (or adjustable) partial grille block using foam pipe insulation. If one day is a lot warmer than another, you can simply remove a section of the foam. On my Insight, I was able to run a 90% grille block in summer.

In winter, I also attached a piece of coroplast to block most of the opening from the wheel well to the engine bay. The primary purposes was to stop salt from being thrown all over, but it had the side benefit of also retaining heat.
