Title: Well it sounds good...
Review: The product did not come drilled for the Mass Air Flow Sensor. I had to spend several hours drilling and carving a hole large enough to allow it to fit. The product show's little improvement (1mpg<)to my mileage (I drive very conservatively as is). Sounds good under the hood, if that is what your willing to pay for. Did notice slight increase in overall engine power, but again, not enough to really make a difference.
