I can definitely tell an increase in throttle response, and fuel mileage gain.

It definitely gives a little better sound to the engine. It would probably be better if the car were a V8. It also makes the car run better and I can notice the horsepower. It also has made smoother shifting because the engine is running better. It was about an hour to remove the stock and install this one. The directions were pretty good but could have used a few more good pictures. I had to look at the overall diagram to figure out a couple small things like the gaskets.

I had a couple of issues with the illustrated instruction sheet. One, there was only a small indentation pre-drilled for the MAS. So, a hole had to be drilled to accomodate the sensor. Second, the filter must be installed from below, and in order to do that the car has to be jacked up, wheel removed and most of the fender liner taken off. Once that is done it is easy. The whole job took well over an hour.
