The Porsche Boxster Fuel Valve / Breather Line (OEM 99611012904) is a used genuine part removed from a donor vehicle. This component, also known simply as a fuel valve or breather line, manages pressure and vapor flow in the fuel system. It is designed for the 2.5L, 2.7L, and 3.2L naturally aspirated H6 engines found in the Boxster. When this breather line fails or the valve sticks, you may notice fuel odor, a rough idle, or difficulty filling the tank due to improper venting.
