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

Vroooom!!
I used to have one of these intake manifolds on my LS1. Years ago I started the process of turbocharging my car and I must have bumped my head on something because I sold it and bought a Holley intake. While Holley does make a nice intake I missed the Fast intake as I felt it was more appropriate for my build. The " best usable" RPM range of the Fast is around 2-7k rpm, exactly where my engine makes power best. It's lightweight, won't heatsoak, and its very well made. For a cathedral port LS engine I firmly believe that this is a solid upgrade. I'm running a 92mm throttle with a velocity ring (which unfortunately can be difficult to find nowadays), and 10lbs of boost. I made sure to follow the directions exactly when installing, boost leak tested it up to 20psi, and did not have a single leak. I'm very happy to have a Fast intake again, the car is running great and making some good power.

Great deal on Amazon
Aside from shipping taking extremely longer than normal due to snow delays. they always come thru with quality. Best intake on the market for you LS. Do your own research.great price and bang for your buck kit on Amazon!

Very misleading
Does not come with the hardware to install the intake. One review said it did but it does not. Make sure to click “what’s in the box” it’ll only state manifold. Poor husband is now doing research to find the correct hardware because the pictures and the description showing the manifold with the hardware. Instruction manual states it comes with hardware but upon further inspection there’s grease all over it and and bolt sticking out. Will be returning if we can’t get this resolved!!
