Amazing
Bought this last year and I cannot be happier. Instructions were easy to follow and had it on within a few hours. If you have regular hand tools you should be able to complete this right away. If you have problems with it, you probably installed it wrong. lol

Fast Customer service is poor at best!
Extremely disappointed with Fast in general, fuel rails do not fit injectors properly after following Fast representatives guidance on product selection, and after repeated attempts to contact Fast there is no resolution, my experience has been extremely negative regarding the following, customer service product quality and installation. Wish I could give it zero or negative stars!

STOCK 99-06 truck throttle bracket works
Nice intake as expected I did look for what bracket would fit before I bought it. Planned on building one but the stock gen 3 truck one fits and has cruise. Overall nice piece. Expensive but everything is.

Good quality part
Good quality part, way over prices and horrible directions and poor customer service at FAST. Go with the new Ellerbrock intake, the Atomic. You will be much happier I think.

Does not fit a 2008 Chevy Tahoe!
We took everything to the professionals to be installed and it's not made for our 2008 Chevy Tahoe. It does not fit at all! Falsely advertised!

Corporate greed galore
Over priced. Greedy company. This cost nowhere near 1.3k$ to produce.
