Description
Precise fuel metering is the foundation of consistent carburetor performance, and worn or mismatched main jets will leave power on the table and create unpredictable running conditions. The Holley 122-87 main jets deliver the exact fuel flow your engine demands across the load range, ensuring optimal air-fuel ratios whether you’re tuning a street engine or dialing in a race carb. These brass jets are purpose-built for Holley carburetors and come as a matched pair, eliminating guesswork in your jetting strategy.
