This is a set of 4, cast, bent rampipes for 40 mm carburetors.
These sets became world-famous when they were used on Alfa Romeo's GTA racing cars.
By means of the special braces (included!) the trumpets can swivel a full 360 degrees and consequently can be adjusted exactly to your personal needs.
Tailor-made for Alfa-Romeo Nord engines, these comes complete with a top quality machined aluminum mounting plate to provide a solid base to secure the two carburetors and maintain the balance between the two.
As visible in the pictures, the trumpets are thick-walled, cast, aluminium with a crimped-on coarse mesh gauze.

The sets are available for 40 mm diameter carburetors and, at a small premium, also for 45 mm.
These sets will fit Alfa Romeo Nord engines equipped with the following carburetors:
