Air Intake Rubber in Rear Panel | 311 119 665A

This rubber intake boot (311 119 665A) sits between the air filter and the carburetor on Type 3s and ensures an airtight connection. After decades, the rubber becomes brittle and cracks, leading to air leaks and a poorly running engine. Replace this rubber when cleaning or tuning the carburetor, as you'll have everything open anyway. Combine this part with a new air filter housing and carburetor service kit for a complete overhaul.
