Why It Matters
The venturi is where a carburetor takes the pulse of the air, and a smaller throat reads it sharper. The 27mm venturi quickens air velocity through an EMPI D Series carburetor, drawing a crisp low-rpm signal on smaller-displacement engines.
The venturi sizes the airflow through the carb throat, which sets the fuel signal and response, so the smaller throat suits engines built for low-end response.
Installation Notes
It drops into the venturi bore; no machining required. Order one per barrel so both barrels can be matched.
