The Item has made a difference in the performance of my vehicle. I am very impressed with it, and it is definitely worth the money. I did not mark (5) stars on installation only because I had my Local ford performance shop install this item (they are professionals, and did it fast and right. Again I am happy I bought it and it helps with my acceleration, Gas savings (I doubt it...LOL, if you wanna go fast, you gotta pay for gas)... No exceptions in that rule. Best Regards, Marcel

Good quality, looks great on my Grand Marquis. I can feel the difference in power and torque, sounds awesome when you get on it. Only negative thing is my check engine light came on after about 100miles for MAF sensor. An afe technician will be contacting me soon on how to resolve this issue. Other than that looks very good under the hood!
