Will comment after install. Overall great product! ### ⭐⭐⭐⭐⭐ Amazing *by on Reviewed in the United States 21 September 2020* 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!! *by on Reviewed in the United States 16 January 2026* 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. ## Frequently Bought Together - FAST LSXr 102mm Intake Manifold for LS1, LS2, and LS6 (146302B), black - COMP Cams O-Ring --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/202451434-fast-lsxr-102mm-intake-manifold-for-ls1-ls2-and-ls6](https://www.desertcart.gr/products/202451434-fast-lsxr-102mm-intake-manifold-for-ls1-ls2-and-ls6) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-09-26*
