Easy install, only had to drill one hole. Everything fit precisely. Filter is enclosed so U do not get engine heat for better performance. Would highly recommend!
Works as advertised. Product delivered on time.

There was a significant increase in gas mileage and noticeable increase in power when driving the mountains of Colorado. I'm not leaving vehicles in the dust, but I can now keep up with them and seem to be faster than the majority. The install was challenging for me; but I'm glad i did it myself. Install time was 2,5 hrs in between watching a football game. If I can install it( anybody can.
