Speedmaster 1-147-026 Ford 351W Windsor HiRise Aluminum Intake Manifold, Polished

The Speedmaster 1-147-026 is a polished aluminum HiRise intake manifold engineered for Ford 351W Windsor engines. This high-rise design increases plenum volume to optimize air and fuel distribution across all eight cylinders, supporting improved throttle response and overall engine performance in street and classic car applications.

Constructed from lightweight aluminum with a polished finish, this manifold delivers both functional benefits and a refined aesthetic for show-quality engine bays. The HiRise architecture is particularly suited to naturally aspirated 351W builds where maximum carbureted or fuel-injected airflow is desired. Compatible with standard 351W Windsor bolt patterns and flanges, it integrates directly into existing fuel and ignition systems without extensive modifications.
