Description

The FAST LSXR 102mm Intake Manifold is engineered for GM LS-based engines, specifically those with LS1, LS2, and LS6 cathedral port heads. This intake manifold utilizes an advanced polymer construction, offering significant advantages over traditional aluminum intakes, including reduced weight, enhanced strength, and superior heat dissipation. Its revolutionary modular design allows for quick and easy disassembly, and individual runners can be removed for custom porting. The LSXR features a 102mm air inlet, optimized to pair with the FAST Big Mouth 102mm Throttle Body, though it can also accommodate stock or aftermarket 90mm throttle bodies with an adapter. Integrated nitrous bungs are included for performance customization. This intake manifold is also 50 State Legal, carrying C.A.R.B. E.O. #D-279-9. Compatibility includes the following applications: '97-'04 Corvette (LS1) and '01-'04 Corvette Z06 (LS6) with drive-by-wire, 3-bolt throttle body; '98-'02 Camaro/Firebird (LS1) with drive-by-cable, 3-bolt throttle body; '04 Cadillac CTS-V (LS6) with drive-by-wire, 3-bolt throttle body; '05-'07 Cadillac CTS-V (LS2) with drive-by-wire, 4-bolt throttle body; '04 Pontiac GTO (LS1) with drive-by-cable, 3-bolt throttle body; '05-'06 Pontiac GTO (LS2) with drive-by-wire, 4-bolt throttle body; and '05-'07 Corvette (LS2) with drive-by-wire, 4-bolt throttle body. Note that all 3-bolt throttle bodies will require an adapter to function with this manifold.
