fast shipping, easy installation. I can feel a better throttle(pedal)response for sure. there is a slight difference in the engine sound, but when you hit the gas is when you do notice it. dont know about better mpg or horsepower but I loke knowing my air filter will last for years with simple maintenance. I also like the better throttle response. I have a flowmaster to install and I am pretty sure I will really gain the full benefits of both. auto anything is a 5 star rating for this purchase.
