Certified Confidence:** Street-legal with D-279-8 approval for hassle-free upgrades ## Overview The FAST LSXr 102mm Intake Manifold is a high-performance, C.A.R.B.-approved upgrade designed for LS1, LS2, and LS6 engines. Featuring a larger 102mm air inlet and longer runners, it delivers 10-25 horsepower gains while preserving low-RPM torque. Its modular, removable runner design allows easy customization and porting. Constructed from advanced polymer, it’s lighter and runs cooler than aluminum alternatives, finished in a sleek black for a modern, aggressive look. ## Description Now available in a sleek, black design, FAST 102mm LSXR and LSXRT Intake Manifolds optimize airflow material and utilize a multi-piece design to provide bolt-on 10-25 horsepower gains. With longer, less restrictive runners and a larger air inlet than stock versions, these FAST 102mm manifolds deliver added horsepower without compromising low-RPM torque. The 102mm low-restriction design yields maximum performance, while a modular, removable runner design allows for easy disassembly and porting. Constructed from an advanced polymer material and featuring an eye-catching black finish, FAST 102 LSXR and LSXRT intakes are lighter than aluminum and run much cooler. The LSXR design is available in three port configurations for LS1/2/6, LS3 and LS7 applications, and is a direct performance replacement to fit stock accessories. Meanwhile the LSXRT is a direct fit for 4.8, 5.3 and 6.0L trucks, as well as engines without clearance concerns. When combined with popular LS upgrades like FAST Big Mouth Throttle Bodies the performance gains are even more pronounced. The manifolds are C.A.R.B.-approved no. D-279-8. Review: Nice Bolt on Mod for More Air!! (2006 Pontiac GTO) - I got this for my 2006 Pontiac GTO. It's a good DIY upgrade and bolts right on. Only modification necessary is to drill a little hole for the MAF, otherwise it goes right in. I'd recommend getting new gaskets while you're in there. As soon as it was installed, I noticed my car pulled harder in 3rd and 4th gear. Definitely would recommend. Review: 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. ## Features - Longer runners & larger air inlet than stock deliver added HP while maintaining low-RPM torque - Available in a sleek black finish for stunning good looks when installed on any LS engine - Modular, removable runner design allows for easy disassembly & porting - Advanced polymer material makes intake lighter than aluminum & run much cooler - C.A.R.B.-approved no.

I installed on a C6 corvette. Easy install, I just watched YouTube videos and not one problem. I would definitely spend the money on the FAST gaskets. Take pics of all your hose connections and should be breeze. I'm running stock air box, stock TB. X4 tune and mainfold together sings very well. ## 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.hr/products/21881929-fast-lsxr-102mm-intake-manifold-for-ls1-ls2-and-ls6](https://www.desertcart.hr/products/21881929-fast-lsxr-102mm-intake-manifold-for-ls1-ls2-and-ls6) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-13*
