Description
The Holley Power Valve 125-165 is engineered to optimize fuel delivery across your engine’s RPM range by responding dynamically to intake manifold vacuum. This single-stage design ensures crisp throttle response at partial throttle while maintaining precise air-fuel ratios during acceleration and cruise. If your carburetor isn’t delivering consistent performance across all driving conditions, upgrading to this high-flow power valve is a straightforward bolt-on solution that makes an immediate difference.
