Description
The accelerator discharge nozzle is a critical component in your Holley carburetor’s fuel delivery system, directly affecting throttle response and off-idle performance. A worn or incorrectly sized nozzle compromises your engine’s transition from idle to cruise, resulting in hesitation and poor drivability. This OEM Holley replacement ensures consistent fuel atomization and precise metering when you demand immediate throttle response.
The hollow design (MPN 121-7) accommodates nozzle sizes starting at 0.040 inches, making it compatible with a wide range of Holley carburetors and tuning configurations. Steel construction delivers the durability required for repeated heat cycling in high-performance and racing applications.
