LSX 92mm Intake Manifold

The FAST LSX 92mm Intake Manifold is a three-piece composite manifold engineered to deliver increased performance for GM Gen III (LS1, LS2, and LS6) engines. Designed to easily bolt on, this manifold works seamlessly with the 92mm FAST Big Mouth throttle body and features a stylish black finish. Its construction utilizes high-strength polymer and includes corrosion-free stainless steel assembly bolts. This manifold boasts a 92mm throttle body opening and a cathedral port style, suitable for engines such as the 5.7L V8 LS1/LS6. It is designed to operate effectively within an RPM range of 1,800-6,000. The design maintains performance gains without compromising bottom-end drivability or high RPM power, and it is rated for boost pressure up to 45 psi continuous. The velocity stacks are tall and can be interchanged with medium or short versions for customization. Included with the manifold are stainless steel bolts and threaded insert throttle body mounts. The manifold's design also allows for potential porting by the customer for further flow enhancement.
