What makes this intake manifold different from an aluminum one?

This FAST LSXR manifold is constructed from an advanced polymer material. This makes it lighter than aluminum, stronger, and it dissipates heat more effectively, which can lead to more consistent performance.

What kind of performance gains can I expect with this manifold?

The LSXR 102mm manifold is designed to provide bolt-on performance improvements, particularly in airflow to the engine. It's intended for street applications and aims to enhance power without negatively impacting low-end drivability.

Does this intake manifold come with all the necessary hardware for installation?

While this manifold is designed as a direct fit for compatible LS engines, it's always best to refer to the manufacturer's installation instructions. These instructions will detail any specific hardware or additional components that may be required for a complete installation.

It's built from an advanced polymer material, similar to the original FAST LSX 92mm manifold, but offers some notable advantages over traditional aluminum intakes. For starters, it's significantly lighter, which can make installation easier and contribute to a better power-to-weight ratio. The polymer construction also helps dissipate heat more effectively than metal, and it's known for its increased strength.

The LSXR 102mm manifold is engineered to provide bolt-on performance improvements without sacrificing low-end drivability, making it a solid choice for street-oriented applications. It features standard design runners that work well for mild builds. This manifold fits a wide variety of GM vehicles, including popular models like the Chevrolet Silverado 1500, GMC Sierra 1500, and Cadillac Escalade, among many others. It's a substantial upgrade for anyone looking to improve their LS engine's breathing and overall performance.

When installing, remember that this is a direct-fit manifold for the specified LS engines. It's a significant component for improving airflow into your engine, and it pairs well with other performance upgrades. Make sure to consult the manufacturer's installation instructions for any specific details or hardware requirements.
