All I can say is wow!!!:yikes:

Helped my cousin out by fixing an idle problem on her 2003 Nissan Altima (with 96000 miles). I went ahead and did a tune-up too. I almost felt bad for the little car The air filter box looked like a bird had set up a nest in there, and the spark plugs were covered in carbon. Replaced the cabin air filter and this is what I found. Keep in mind, the filter is located right behind the glovebox.

Dirty one...

New one...

My e34 doesn't have one, I did our e36/5 once a year and the e46 will get changed at inspection 1 or about 30 months.
