The quality of this product is without question.I did have a bit trouble to put it in my stock air box. It was as if the size oaf the filter was not right. I put it against to OEM filter and it looked like it was a bit bigger. However this just made the filter to fit snug in the box sealing well on all corners. I have not noticed yet mpg improvement, but it hasn't been that long. I did notice that the engine was holding higher rpms a bit longer making the engine appear more responsive.

I was staying at a B&B in Key West. And was told about this outstanding filter. Better than original was the claim. I kind of doubted the claim. But it was time to change the filter on my BMW. So I figured why not give it a try. To my doubting mind I was amazed at the immediate increase in car power. I asked my wife to drive the car. Same overall comment from her also. Have not had the filter on the car long enough to say if it also increases my gas milage but from initial observation it has not hurt it.
