This Heater Tube Inside Sill is a Genuine Porsche OE component designed to route heated air through the inner sill section of classic air-cooled Porsche 911 models from 1969 to 1989. The heater tube carries warm air produced by the engine’s heat exchangers through the sill cavity toward the cabin ventilation system.
Fits:
Porsche 911 1969 - 1989
Diagram ref no 15
Function: Installed inside the vehicle’s sill structure, the tube forms a critical part of the classic 911 heating system. It channels heated air forward into the cabin ducting, supporting effective interior heating, windscreen demisting, and overall comfort in cooler conditions.
Over time, original heater tubes can degrade due to heat cycles, age, and corrosion, resulting in reduced airflow or heat loss before reaching the cabin. In severe cases, damaged ducting may allow unwanted fumes or debris into the heating system. Replacing the tube with a Genuine Porsche part restores factory heating efficiency, preserves originality, and ensures long-term reliability of the heating system.
Replace this heater tube if you notice:
• Weak or uneven heater output
• Cracked, brittle, or collapsed ducting
• Heat loss before air reaches the cabin
• Unpleasant odours from the heating system
• During restoration or refurbishment of the sill or heating system

This heating tube inside sill is a high-quality replacement air-duct tube designed to channel warm air from the exhaust-heated heating system through the sill area of classic Porsche 911 models built from 1969 through 1989 and 356 B/C models. It matches the original part’s fit and performance to maintain proper heating airflow in your vehicle’s cabin.
Fits:
Porsche 356 B/C 1.6 01/1959 - 12/1965
Porsche 911 2.0-3.3 08/1968 - 07/1989

Porsche 914 1.7-2.0 01/1969 - 07/1974

The heating tube directs hot air generated by the engine’s exhaust-heated heat exchangers into the cabin area via the sill ducting. This ensures your classic Porsche’s heater system distributes warmth effectively, improving defogging, defrosting, and passenger comfort in cooler weather.
Function: Installed along the inner sill section, this tube captures heat from the heater system and delivers it through the duct network into the footwell or cabin air distribution points. A properly functioning heater tube helps maintain consistent cabin temperature and prevents heat loss due to damage or age-related degradation of the original ducting.
Over decades of use, original heater tubes can become cracked, brittle, or collapsed, leading to poor airflow, heat loss, or even exhaust gas intrusion into the cabin air system. Replacing the deteriorated tube with an OE Match unit restores effective hot-air distribution, improves cabin comfort and heater efficiency, and keeps the vintage heating system functioning as intended.
Replace this heating tube when you notice:
• Weak or inconsistent warm air delivery from the heater
• Deteriorated, cracked, or collapsed heater tubing
• Excessive heat loss before reaching the cabin
• Unusual smells from heater ducts (possible leaks)
• During full heater system or sill restoration work
