Product was as described. Installation was quick and easy. Looks good under the hood too!. I was a little disappointed that there was no noticeable difference in performance or mileage. It is hard to justify a purchase that claims results but is difficult to quantify. I measured in town and over the road. It could just be my expectations were to high. In all fairness, I am not getting worse mileage so small changes over time will make a difference.
