Genuine 946-106-026-61 Porsche Coolant Distribution Pipe OEM Vent Line

The Genuine Porsche 946-106-026-61 is an OEM coolant distribution pipe, also commonly referred to as a coolant vent line or water distribution pipe. This component plays a critical role in the engine cooling system by routing coolant between the cylinder heads and the cooling circuit, helping maintain proper engine operating temperatures.

As a factory-original Genuine Porsche part, this pipe is manufactured to the same specifications as the component originally installed at the factory, ensuring precise fitment and reliable long-term performance. Over time, the factory-installed plastic vent lines can degrade due to sustained high operating temperatures, becoming brittle and susceptible to cracking or leaking — making timely replacement essential to preventing coolant loss and potential overheating.

• Direct factory-spec replacement — no modifications required
