Speedmaster 1-147-098 Oldsmobile 400 425 455 Low-Rise Aluminum Intake Manifold Polished

The Speedmaster 1-147-098 is a low-rise aluminum intake manifold designed specifically for Oldsmobile 400, 425, and 455 cubic-inch V8 engines. Constructed from aluminum, it offers a lighter weight alternative to factory cast-iron units while the polished finish delivers a clean, show-quality appearance under the hood.

The low-rise profile makes it well suited for applications where hood clearance is a concern, and the design is intended to support improved airflow and throttle response on Oldsmobile big-block builds. A direct-fit solution for enthusiasts looking to upgrade the induction system on their Olds-powered project.
