Designed for high-RPM performance, the Certified Automotive Experts High-Rise Single-Plane Air-Gap Intake Manifold is built for carbureted Ford Small Block Windsor 289 and 302 cubic-inch engines with standard deck height.
Its single-plane, open-plenum configuration is designed to support increased airflow at elevated engine speeds, with a specified operating range of approximately 3,500–8,000 RPM. The air-gap design helps isolate the intake runners from engine heat, supporting cooler intake air temperatures during demanding driving conditions.
Featuring a square-bore four-barrel carburetor flange compatible with 4150 and 4160-style carburetors, this manifold is suited to compatible naturally aspirated performance street, street/strip, hot rod, and muscle car builds.
The polished aluminum construction adds a refined appearance to exposed engine bays. Designed for carbureted applications, this manifold does not fit Boss 302 engines, EFI intake systems, or applications requiring EGR provisions.
