Do any of you have this? I wanna know what your thoughts and experiences are on it. does that big red piece have to take place of the plastic OEM cover? any effects in noise? mpg? performance? I'm curious.
I don't have a lot of time to reply, but I do have some input. The red cover looks optional. A user here quite some time ago put one of these on his car. He didn't yield any better MPG but apparently the car (engine) was a tad quieter and that's about it. Don't do it. I wouldn't, at least.
