Was bored this evening, so I decided to change out the spark plugs, air filter and cabin filter. When I took out the cabin filter, the housing had tons of leaves :rolleyes: . I wonder how it got there???

Here is a pic of the old air filter. I wonder if BMW ever changed the thing out during its maintenance warranty...

Since I had the airbox apart to vacuum up the dirt, I decided to clean the MAF sensor...

And finally, changed out the plugs. Here is a pic of the plugs after 50,000 miles....

I know I could have waited another 40-50k miles or so to change them, but I wanted to give the X a clean bill of health.
