Intake Manifold, FiTech Retro LS1 Port, Cast Aluminum, w/Fuel Rails

Chevrolet LS1 Retro-LS Cast Intake Manifold with 4150 Flange and Fuel Rails by FiTech®

A 4150-style top flange gives an LS induction system the traditional carburetor-and-air-cleaner layout.

This FiTech® Retro-LS LS1 intake combines a machined cast-aluminum manifold with billet fuel rails. The 4150-style top flange positions a compatible throttle body where a traditional four-barrel carburetor would sit, allowing the familiar round-air-cleaner appearance on an LS engine. The manifold and rails provide the induction hardware for a port-injection build without dictating the injector size. The intake is designed to support engine airflow and fuel delivery. Fuel injectors are not included.
