Once installed this intake makes a noticeable difference in the performance of this car. The throttle response is much quicker and smoother than with the factory air filter system. It is too new to determine gas mileage, but for drivability it is worth the cost. However, the 20 minute installation window seems to be a bit un-realistic. Allow twice the time.
