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.
