Manufactured to exact Porsche specifications with precision bore, correct fit and finish, this OEM part ensures correct mixture delivery, consistent idle behaviour and restores original equipment performance in your classic Porsche fuel system.

Replace this part when:
•  You are performing a full carburettor rebuild or fuel-system service
•  The original is worn, corroded or missing
•  The engine shows symptoms of mixture imbalance or idle instability
•  You aim to restore the vehicle to factory specification and optimal performance

Installing the genuine Porsche restores original induction geometry, precise mixture control and ensures your classic Porsche runs the way Porsche intended.
