Filter installation is easy. Function....well, it's a filter that you never have to throw away, that is great in and of itself. In terms of improving motor function, well, I went from 14.3 mpg to 18 for about 2 days and then over about 2 weeks it ended up to about 15 mpg. So, not a huge improvement but like I said, it's a filter I'll never have to replace and it helped with mpg a little, so, all in all, I'm happy with it.
