Product Description
The BILT 2 PERFORM GM LS Rectangle-Port EFI Single-Plane Intake Manifold Kit combines the major induction and fuel-delivery components needed to build a high-performance EFI intake system for compatible Chevrolet LS rectangle-port engines. The package pairs a cast aluminum single-plane intake manifold with a 4150-flange throttle body elbow, 102mm 4-bolt LS throttle body, and a matched set of eight high-flow fuel injectors.
The single-plane manifold provides a performance-oriented intake configuration while retaining electronic fuel injection through integrated fuel rails and injector provisions. The 4150-flange elbow converts the manifold's top-mounted opening to accept the included 102mm LS-style throttle body, creating a complete induction path in one coordinated package.
Choose from Satin, Polished, or Black intake configurations to match your engine build. Injector flow rate is also selectable, allowing the kit to be configured around different 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.
