Velocity Stack Air horn ram pipe trumpet WEBER 48 IDF 45/48 DCOE 35mm
$ 32.3
Part number: ST2723
Made in: EU
Velocity Stack Air Horn Ram Pipe Trumpet for Weber 48 IDF and Late 45/48 DCOE – 35 mm
This bolt-on air horn mounts to the carburetor inlet and provides a shaped entry for airflow into the 48 mm throttle body. It is used with Weber 48 IDF carburetors and late Weber 45/48 DCOE carburetors.
The velocity stack supports a smoother air approach into the throttle bore and can influence inlet-flow quality and transient response. It is an airflow component, not a fuel-metering part, so it does not replace or alter jets, emulsion tubes, or fuel-level settings. A damaged, missing, or mismatched air horn can create an uneven inlet transition and may also affect available air-filter clearance.
48 mm internal diameter with 35 mm total length. The air horn has a polished alloy finish and is supplied for bolt-on installation at the carburetor air-entry side. MPN: AH4835BO.
This replacement part is suitable for carburetor service and restoration work where the original component is worn, damaged, or missing.
Reference/MPN: AH4835BO.

Important Fitment Note
Verify the carburetor family and body size before ordering: this part is intended for Weber 48 IDF and late Weber 45/48 DCOE applications with 48 mm throttle bodies. Compare the 48 mm internal diameter, 35 mm overall length, flange geometry, mounting-hole pattern, and seating surface with the removed air horn or carburetor inlet. Also check the available air-filter or intake clearance and confirm that the mounting interface accepts the bolt-on air horn.
Compare the removed part and verify the carburetor code or marking before installation, especially on modified or mixed-generation Weber assemblies.
