Designed for the Porsche 911 turbo (930) and Porsche 964 turbo, this hose connects the engine cooling fan housing to the left-hand heat exchanger, delivering the airflow required for the vehicle's heating system. Manufactured from durable, heat-resistant materials, it provides the correct fit and flexibility needed to withstand the demanding temperatures of the engine bay.

Whether you're replacing a deteriorated original hose or completing a full engine restoration, this OE Match component restores factory-style performance and appearance.

What Does the Engine to Heat Exchanger Hose Do?

The engine to heat exchanger hose is an essential part of the air-cooled Porsche heating system.

Its primary functions include:

Directing cooling fan air from the engine to the left-hand heat exchanger.
Providing the airflow required to generate warm air for the cabin heating system.
Maintaining efficient airflow through the heat exchanger.
Helping ensure effective windscreen demisting and cabin heating.
Completing the sealed airflow path between the engine and heating components.

Without an airtight hose, airflow is reduced, resulting in diminished heating performance and reduced system efficiency.

Why Does the Heat Exchanger Hose Fail?

Located in the engine compartment, the hose is constantly exposed to high temperatures, engine vibration and environmental contaminants.

Common causes of deterioration include:

Heat-related hardening and cracking.
Rubber or reinforced material becoming brittle with age.
Splits caused by engine movement and vibration.
Damage during engine maintenance.
Oil contamination reducing material strength.
General wear after years of service.

A damaged hose allows cooling air to escape before reaching the heat exchanger, reducing heating efficiency and affecting overall airflow management.

When Should It Be Replaced?

Replacement is recommended when:

The hose is cracked, split or torn.
Heating performance has noticeably decreased.
Air leaks are present within the heating system.
The hose has become brittle or collapsed.
Carrying out an engine or heating system restoration.
Replacing heat exchangers or other heating system components.
Performing preventative maintenance on older vehicles.

Replacing ageing heating hoses helps restore proper airflow, improve cabin heating performance and maintain the efficiency of the air-cooled heating system.
