Edelbrock 54039B LSX 92mm Black Intake Manifold

The Edelbrock 54039B LSX 92mm Black Intake Manifold (FAST) is a three-piece Gen III composite intake designed to add power without giving up low-end drivability or high-RPM performance. Built as a straightforward bolt-on for GM LS1/LS2/LS6 engines, it’s aimed at both street builds and dedicated race setups—especially when paired with a FAST Big Mouth 92mm throttle body.

This black LSX manifold includes durability and sealing upgrades like corrosion-resistant stainless assembly bolts, a refined throttle body sealing flange with an O-ring gasket, and threaded insert throttle body mounts for long-term strength. The polymer composite construction also helps resist heat soak compared to aluminum, and it can be customer-ported if you want to chase even more airflow. It’s designed to help you get more out of common performance upgrades like cylinder heads while maintaining strong torque and drivability.

For both street and racing applications, the composite FAST LSX 92mm Black Intake Manifold is an easy bolt-on installation for GM LS1/LS2/LS6 engines.
