Dominator HP #25 Air Bleed

The Dominator HP #25 Air Bleed from Holley is a precision carburetor tuning component designed specifically for high-performance fuel system calibration. This air bleed jet is crucial for achieving precise fuel atomization and controlling the air-fuel mixture, which is essential for optimal engine performance in various applications, including street machines and track vehicles.

Air bleeds function by introducing a controlled amount of air into the fuel circuit, which reduces fuel density and enhances atomization in the carburetor's emulsion tubes and discharge nozzles. The #25 designation specifically refers to the size of the air bleed jet, which is calibrated for mid-range performance applications, making it suitable for street and street-strip engines where balanced fuel delivery is critical.

This air bleed is particularly beneficial for tuners working with Holley Dominator HP four-barrel carburetors on naturally aspirated, moderate to high-displacement engines. Proper installation requires carburetor disassembly, allowing enthusiasts to customize their setups without needing to replace entire carburetor assemblies.
