Description
Air bleeds are critical calibration components in Holley carburetors—they control fuel atomization and air-fuel mixture ratios across the entire RPM range. Installing the correct size air bleed is essential for tuning consistency, whether you’re dialing in a street engine or fine-tuning a race carb for peak performance. This set of ten #57 brass air bleeds gives you multiple sizes to experiment with and dial in the ideal mixture curve for your specific engine combination.
