EMPI 28mm Main Venturi (44-1105-0) for EMPI D Series Carburetors
The EMPI 44-1105-0 is a genuine 28mm main venturi for EMPI D Series (EPC) carburetors, including those on the 1970-1976 Porsche 914 and air-cooled VW engines. The 28mm bore balances low-end signal with mid-range flow, a common step up from 27mm on mild street engines. It drops into the venturi bore without machining and is sold each, so you can match left and right sizes.

Why It Matters
A single millimeter of throat trades a little low-end urgency for a cleaner middle. The 28mm venturi opens airflow through an EMPI D Series carburetor just enough to broaden a mild street engine's powerband.
Installation Notes
The venturi drops into the venturi bore of an EMPI D Series carburetor with no machining required. It is sold each, so order one per barrel to keep both barrels matched.
