Very rare pair of Weber 40IDS carbs for Porsche 6 cylinder engines. Can be used up to 3.0 liter engines. IDS carbs have  a special extra jet for full throttle applications that allows for extra gas to be sent into the cylinders under full load. This give the engine more power and prevents lean situations at high RPM ranges.

Carbs come complete with linkage, PMO fuel rails, intake manifolds, high flow filters and rain hats. Currently jetted for 2.7 liter stock engine.  Runs great and smooth.
