Carb Insert 2in Tall Open

The Carb Insert 2in Tall Open from Wehrs Machine is a precision carburetor velocity stack insert designed for serious engine builders and performance enthusiasts who demand maximum airflow efficiency. This component is specifically tailored for four-barrel carburetors, addressing a critical need in high-performance carburetor tuning: optimizing the air column entry into the carburetor throat while maintaining proper fuel atomization.

The 2-inch tall open design creates an optimized velocity stack that guides incoming air smoothly into the carburetor bore, reducing turbulence and improving the quality of the fuel-air mixture at idle and light throttle conditions. The open configuration allows for unrestricted airflow while the geometric profile manages air velocity through the transition zone. Precision-machined from quality materials, Wehrs Machine's carburetor inserts are engineered to tight tolerances, ensuring consistent fitment and repeatability across multiple carburetors.

This insert benefits carburetor enthusiasts, engine builders, and racers who are optimizing naturally aspirated performance. The relatively light weight of 0.8 pounds means minimal impact on overall engine bay mass while delivering functional performance gains that translate to better fuel distribution and engine response.
