Wide Compatibility: Specifically designed Fit for Holley carburetors, and also fits AED, Barry Grant, Quick Fuel, Demon, Avenger carburetors. It is a dedicated jet kit for engine fuel system upgrade and repair, meeting the needs of various engine tuning scenarios
Premium Quality Performance: Made of high-purity brass with a golden finish, ultra-precise dimensions and tight tolerances. Brass material offers excellent wear resistance, corrosion resistance, and thermal conductivity—effectively preventing deformation, and aiding in fuel atomization for long-term stability of the fuel system
Precise Fuel Control: Accurately meters fuel flow to ensure consistent engine power output under all operating conditions. This not only improves power output stability, and effectively prevents engine idling instability or power fluctuations caused by orifice diameter deviation. The full range of 50-59 sizes meets diverse fuel metering needs for different working conditions
Tuning Tip: When tuning your carburetor to adjust the air/fuel mixture, we recommend starting with a larger gas main jet size and gradually reducing it to your desired specification. This tuning method effectively minimizes the risk of engine damage, ensuring a safer, more efficient process while helping you achieve optimal air/fuel balance
