[ EDIT: from MetroMPG - I made a mess splitting this topic into a new thread. I had to "quote" some users' posts below to move their comments over here. But the quotes below are the original words made by the person quoted. ]
I've also noticed that I've gotten a slight but noticeable increase in fuel economy after replacing my OEM Air filter to a K&N Filter.
