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.
