Performance Benefits & Key Features

FAST LSXR 102mm Intake Manifolds are engineered to significantly improve airflow, one of the most critical factors in increasing engine performance. Featuring a large 102mm throttle body opening and high-flow composite runners, these manifolds are designed to deliver more air to the engine, supporting increased horsepower and torque—especially in the mid-to-high RPM range.

Constructed from advanced composite materials, these intake manifolds offer excellent heat resistance, helping to reduce heat soak and maintain cooler intake air temperatures. This contributes to more consistent performance under demanding conditions. The optimized runner design enhances airflow velocity and distribution, improving combustion efficiency and throttle response.

Key specifications include compatibility with larger throttle bodies, high-flow fuel rails, and performance cylinder heads. These manifolds are ideal for engines producing 500+ horsepower, depending on the overall setup. The lightweight construction also helps reduce overall engine weight while maintaining durability and structural integrity.

For performance enthusiasts, the result is improved acceleration, stronger top-end power, and enhanced engine responsiveness. Whether naturally aspirated or paired with forced induction, the LSXR 102mm intake provides the airflow needed to support serious performance upgrades.

Fitment, Compatibility & Applications

FAST LSXR 102mm Intake Manifolds are designed for GM LS-based engines, including popular platforms such as LS1, LS2, LS3, and LS6. This makes them a versatile upgrade for a wide range of vehicles, from modern muscle cars to custom LS swap projects.

Ideal for street performance, drag racing, and track applications, these intake manifolds are commonly used in Camaros, Corvettes, GTOs, and high-performance trucks. They are also a popular choice for LS swap builds in classic muscle cars and restomod projects, where maximizing airflow and power is a priority.

These manifolds are compatible with aftermarket tuning solutions, allowing users to fully optimize performance gains through ECU calibration. Their design ensures proper fitment with supporting components, making them a key upgrade in high-performance engine builds.
