Holley Main Jets (2) 122-67

Precision fuel metering is fundamental to carburetor performance, and worn or incorrectly sized main jets directly compromise throttle response, fuel economy, and engine reliability. These Holley main jets deliver consistent atomization and fuel delivery across the mid-range and cruise bands—critical for both street tuning and track applications. If you're rebuilding a Holley carburetor or fine-tuning your air-fuel ratio, a quality jet set ensures repeatable performance and eliminates guesswork.
