Velocity Stack Air Horn Ram Pipe Trumpet Slide-In for Weber 40 DCOE
This velocity stack, also called an air horn, ram pipe, or trumpet, fits the inlet side of a Weber 40 DCOE carburetor. Its bellmouth-style entry guides incoming air smoothly into the carburetor, supporting cleaner airflow into the main and progression circuits than an open, abrupt inlet.
The slide-in design uses the carburetor’s air-entry interface rather than changing the fuel metering components. MPN 52840.012S identifies this Weber 40 DCOE velocity stack. Because the air horn influences inlet airflow and transient response, check the carburetor’s air-entry condition and confirm that surrounding clearance is suitable before installation.
This replacement part is suitable for carburetor service and restoration work where the original component is worn, damaged, or missing.
Reference/MPN: 52840.012S.
Technical role: Slide-in velocity stack air horn for the inlet side of a Weber 40 DCOE carburetor, guiding intake airflow through its bellmouth entry.
Service relevance: Supports smoother inlet airflow without changing the carburetor’s fuel-metering components, while requiring inspection of the air-entry interface and surrounding clearance.

Important Fitment Note
Verify the carburetor family and confirm the 40 DCOE identification before ordering. Compare MPN 52840.012S with the required part reference, then check the removed air horn or carburetor inlet for matching slide-in geometry, mounting interface, seating arrangement, and available clearance.
Always compare the inlet profile and interface with the removed part before installation; Weber DCOE components can vary by version and application.Show all parts
