Weber Dual 40 IDF-XE Carburetor Kit for Porsche 356 and 912

This carburetor kit is for off-road and racing use only and should NEVER be used on the highways in California.

With its central float chambers, full calibration capabilities, compact alloy body and wide variety of available sizes, the IDF Series has been and continues to be the winning choice for a synchronous, 2 barrel, downdraft carburetor.

The IDF features diaphragm type accelerator pump circuits and ball bearing throttle shafts. When used with an adapter, the IDF will replace the Solex 40 PII carburetors.

The IDF is ideal for use on most opposed-cylinder engines, or on engines using IR designed intake manifolds. The IDF offers relative low cost for performance gained, the IDF is hard to beat.
