This upgrade works best with the addition of a cold air intake system, really no point in doing without either. The open flow can be felt as soon as you mesh the throttle. I would definitely recommend this to someone looking to add some power underunder the hood without letting everyone around you know you have it. Also if you do this with a tune up get ready BC you will have a space craft.

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
