15K mile service improvements

One reason why the car may feel like its running better is the change in air filter. Here is what mine looked like at 14,000 miles (this is after picking off a couple of twigs with leaves that I find hard to believe were sucked in through the lower intake).

Quite amazing how much debris is vaccumed up by the engine, but I remember reading it inhales a lot of air.

I am going to make it a habit now every couple of months to open the air cover and pick off the big stuff, and I may change air filters with every oil change rather than every 2nd.
