It was packaged well,and the instructions were clear. I would have given 5 stars on installation, but the air box was 1/2 to 3/4 inch too tall. I had to cut it down so that my hood would close properly. It is noticeably louder with engine noise, but I've noticed about 4/10 mpg increase, if I keep my foot out of it.
