Answer 1

Many new cars have them. They are usually located under the dash, so you change them from the inside. I know that GM started using them in like 2000 and I changed one in a 2007 Honda Accord last week. Even my 92 Mercedes has them. Manufactures recommend changing them once a year.  

Answer 2

some cars have air filters. check the owners manual.
