Edelbrock Primary Metering Jets

Edelbrock Primary Metering Jets are precision carburetor metering jets, also called main jets, designed for Edelbrock carburetors such as the Performer and Thunder Series AVS. The primary jets control how much fuel flows through the primary side of the carburetor. Swapping jets lets you fine-tune the air/fuel mixture for your engine, its modifications, and the altitude and weather where you drive.

Key Features:

• Calibrated orifices that meter fuel consistently for predictable mixture control
• Used for tuning primary circuit fuel delivery to improve throttle response, power, and drivability
• Direct replacement for worn, damaged, or incorrectly sized jets
• Made by Edelbrock, a long-time name in carburetors and performance induction
• Installs with basic hand tools, with no carburetor modification needed

Whether you are fixing a lean or rich condition or fine-tuning a performance build, Edelbrock primary metering jets give you a simple, affordable way to dial in carburetor calibration. Choose the jet size that matches your tuning needs.
