Designed for carbureted 221, 260, 289, and 302 Ford Windsor engine applications, this polished aluminum intake manifold combines the low-end torque and drivability of a traditional dual-plane design with the airflow advantages of an air-gap intake manifold. It is an excellent choice for street performance builds, classic Mustangs, hot rods, restomods, street trucks, and weekend strip applications.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe air-gap plenum design creates an open space beneath the intake runners to help reduce heat transfer from the engine into the air\/fuel mixture. By helping maintain a cooler intake charge, the manifold supports improved combustion efficiency, throttle response, and power production throughout the RPM range. Unlike many race-oriented intake manifolds, the dual-plane configuration maintains excellent street manners while supporting strong mid-range and upper-RPM performance.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eEngineered to perform best from approximately 1,500 to 6,500 RPM, this intake manifold delivers a broad power curve suitable for everything from daily-driven classics to street\/strip combinations.
