It took a little bit to install it. The hose coming off the water pump got in the way a bit so it's a tight fit. You might need an extra set of hands. I could definitely tell a difference in responsiveness. Didn't really change the mpg's. But it did what I wanted it to. Definitely worth the 80 bucks.
