Speedmaster 1-147-050 Ford Small Block 289 302 Windsor Air Gap Intake Manifold Polished

The Speedmaster 1-147-050 is a polished aluminum mid-rise intake manifold designed for Ford small block 260, 289, and 302 Windsor engines. This performance intake manifold features an innovative air gap design that separates the plenum chamber from the engine block, creating an open space that allows cooler ambient air to circulate underneath.

Air Gap Design Benefits:

• Reduces heat transfer from the engine to the intake charge
• Delivers cooler, denser air to the combustion chambers
• Increases horsepower and torque output
• Features the same proven plenum and runner design as standard mid-rise manifolds
• Polished aluminum finish for enhanced engine bay appearance

The air gap configuration works by isolating the intake runners from engine heat, ensuring maximum air density for improved performance. This manifold is ideal for street and street/strip applications where power gains and consistent performance are priorities.
