Quick Identification and Easy Installation

Each nozzle is clearly engraved with the size (e.g., "50") on the side, along with both inches (e.g., 0.050") and millimeters (e.g., 1.27mm). It uses a 1/4"-32 standard thread and can be installed using common carburetor tools. Simply align the threads and gently tighten. No special tools are required

Simplified Tuning Process

The set includes 10 common sizes (two of each), allowing you to quickly swap nozzles of different sizes for comparison testing during tuning. This eliminates the need to purchase individual nozzles, significantly improving carburetor tuning efficiency

Improves Fuel Economy

Precise fuel metering helps optimize fuel consumption and prevents overspray. Long-term use reduces vehicle operating costs and protects internal engine components

Tool-Free Installation:

The 1/4-32 standard thread accepts common carburetor wrenches. Simply align the threads and gently tighten. No special tools are required, making replacement and tuning easy
