"This is my second Green Air Filter purchase. I have it on my new 2009 GMC Sierra and my wife's 2006 Mustang GT. They are easy to maintain and give your vehicle more air flow than traditional paper filters and help protect the environment for those who are interested. I saw a display of the Green filter vs. a K&N and the difference of air flow was very evident. Green filters are about the same price so it is a no-brainer. The only knock is that you really have to search for the application to some makes and models. It is worth it in the end.
