Product Description
The BILT 2 PERFORM GM LS Rectangle-Port EFI Single-Plane Intake Manifold Kit combines a performance-oriented induction package with a lightweight carbon-fiber throttle body elbow and selectable high-flow fuel injectors. Designed for compatible Chevrolet LS rectangle-port engines, the kit brings together the intake manifold, throttle body, elbow, and fuel injectors in one coordinated package.
The black aluminum single-plane EFI intake manifold features integrated fuel rails and is paired with a carbon-fiber 4150-style intake elbow. A black 102mm 4-bolt LS throttle body completes the induction side of the package, providing a large-bore airflow path for performance LS combinations.
Choose from multiple injector flow rates to configure the package around your engine's fuel-delivery requirements.
Available Fuel Injector Flow Rates:
36 lb/hr • 52 lb/hr • 60 lb/hr • 80 lb/hr • 100 lb/hr • 130 lb/hr • 160 lb/hr
Select the appropriate injector flow rate for your engine combination, fuel type, horsepower requirements, and fuel-system configuration.
