FAST LSXr 102mm Intake Manifold for LS1, LS2, and LS6 (146302B), black

Ok delivery in this crazy COVID times.. love the look.. haven’t installed as of yet. Will comment after install. Overall great product!

Manifold is good remember you need more custom hoses and wires and injector spacers and you need too shave a part of your throttle body too fit it overall really nice manifold.

excellent quality and fit. guarantee to provide more power with other upgrades such as head and cam. recommended for anyone who has a LS motor. you can't beat any aftermarket intake against a fast manifold.

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

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.
