This OE Match Blower Hose is a high-quality replacement component designed to replicate the original Porsche heater hose used in classic air-cooled 911 models. Installed in the engine bay, this hose connects the blower motor to the heat exchanger, enabling the transfer of warm air into the vehicle’s heating system.

This hose, approximately 60 mm in diameter and approximately 1 meter long, is designed for proper routing and fit within the limited space of the engine compartment. It plays a crucial role in maintaining proper cabin heating performance, especially in colder driving conditions.

This blower hose channels heated air from the engine-mounted blower to the heat exchangers, ensuring warm air is properly distributed through the vehicle’s heating system.

Function
•  Transfers heated air from blower to heat exchanger
•  Maintains consistent airflow within the heating system
•  Withstands high engine bay temperatures
•  Flexible design allows correct routing and installation
•  Supports effective cabin heating performance

Over time, blower hoses can become brittle, cracked, or collapsed due to prolonged exposure to heat and age. This can lead to reduced airflow, poor heating performance, and potential heat loss within the system. Replacing a worn hose ensures efficient heat transfer, improves cabin comfort, and maintains proper operation of the vehicle’s heating system.

When to replace
•  Visible cracks, splits, or deterioration
•  Reduced or inconsistent cabin heating
•  Hose becoming brittle or collapsing under heat
•  During engine bay or heating system restoration
•  Signs of air leaks or disconnected ducting
