Description

The FAST LSXR 102mm Intake Manifold is engineered from an advanced polymer composite, offering distinct advantages over traditional aluminum intake manifolds. This material choice results in a lighter weight component, enhanced structural integrity, and superior heat-dissipating characteristics. Designed for LS1, LS2, and LS6 engines with Cathedral Port cylinder heads, it features a 102mm air inlet that is optimized for the FAST Big Mouth 102mm Throttle Body, but is also compatible with stock or aftermarket 90mm and 92mm throttle bodies. Beyond its material benefits, the LSXR manifold incorporates integrated nitrous bungs, providing a convenient platform for nitrous oxide system installation. Its design ensures a perfect bolt-on fitment, accommodating factory accessories without requiring modifications or causing clearance issues. This makes for a straightforward installation process, reducing the need for additional parts or fabrication. The manifold comes with a 12-month warranty and is available in a black finish. It is emissions legal with CARB EO Number: D-279-10.
