I drove it the same as i always do. 1000 miles probs isn't enough to really say but seeing as she only has 3300 miles I couldn't really do longer test. For $130 I'd say do it. It likely doesn't make too much of a difference but for $130 you can't expect too much of a gain.
Thanks for the update. For $130 and 1 mpg its bound to pay for itself in time.. not sure how long that would be.. 130 miles? Not long at all. I want one now. We all bought our cars new so im sure we all plan on keeping them for a while. As far as the rpm range.. thats exactly where my five speed impreza could use some help. Uuh Perrin, if youre tuning in, can we get a group buy on these please?
