Installed a new cabin air filter this morning. Only the 2nd time I've done that service since I bought the car back in OCT/2008. First time was in 2011. The filter was pretty dirty, which surprised me somewhat since I don't put that many miles on the car every year. Anyway, should be good-to-go for another 4-5 years.

I did find out that I'm not meant to contort in those positions to do this service!
