Hot air hose, Heat exchanger to air filter housing. Porsche 911 / 912 / 914 65-71  ❭  90110829100

Hot air hose, heat exchanger to air filter housing. 35 mm X 780 mm.
The OE Match Hot Air Hose is a flexible engine ducting hose designed for classic Porsche models. It connects the heat exchanger to the air filter housing, allowing warm air to be directed into the intake system.

Fits:
Porsche 911 / 912 / 914 (1965 - 1971)

Please note: Two needed for 1968-1969.

The hose channels warm air from the heat exchanger into the air intake system, helping the engine reach optimal operating conditions more quickly. This improves fuel vaporisation and engine efficiency during cold running.

Without proper airflow through this hose, cold start performance and drivability may be affected.

Function
•  Transfers warm air from heat exchanger to air filter housing
•  Supports cold start performance and engine warm-up
•  Improves fuel vaporisation in carburettor/injection systems
•  Maintains correct airflow within intake system

Over time, hot air hoses can become brittle, cracked, or collapsed due to heat and age. This can reduce airflow efficiency and impact engine performance, especially during cold starts.

Replacing the hose restores proper airflow, improves engine efficiency, and helps maintain the correct operation of the intake system - particularly important for classic carburetted engines.

When to replace
•  Cracked, brittle, or split hose
•  Collapsed or restricted airflow
•  Poor cold start performance
•  Missing or disconnected ducting
•  During engine bay restoration or service
