FAST LSXRt Manifold LS3 102MM High HP Runner - Black

This FAST LSXRt 102mm High HP intake manifold is built for LS3 and L92 engines that use rectangle-port cylinder heads. It's designed to give your engine more plenum volume, which is especially beneficial for all-out racing applications and high-RPM performance builds. If you're looking to extract maximum power from your LS3, this manifold is a solid option that has shown proven gains of over 30 horsepower at high RPM compared to the FAST LS3 Street Manifold.

The design features a raised 102mm throttle body location. This placement works in conjunction with the larger, less restrictive High HP runner design to optimize airflow and create more power. A practical benefit is that it also clears truck drive accessories, making installation more straightforward on many GM trucks and SUVs. This manifold is constructed from durable materials and finished in black, giving your engine bay a clean, performance-oriented look.

This intake manifold fits a wide range of GM vehicles equipped with compatible LS3/L92 engines, including popular models like the Chevrolet Camaro, Corvette, and GMC Sierra. It's important to note that this part is not CARB approved and cannot be shipped to California. For optimal performance, ensure you are using a 102mm throttle body, as this manifold is specifically designed to work with that size.
