Information
Engine to heat exchanger hose, 380mm x 60mm.
This is a high-quality replacement hot-air hose connecting the engine fan duct to the heat-exchanger in classic Porsche models. With an internal diameter of 60 mm and a length of 380 mm, this hose replicates the original specification, including the aluminium-lined construction and brown-paper exterior that Porsche used.
Fits:
Porsche 912
Porsche 911 1965-73
Engine to Heat Exchanger on the Left or Right
Fits:
Porsche 930 Turbo 1975-89
Porsche 911SC

Engine to Heat Exchanger on the right
Diagram ref no. 20
• Position on Vehicle: Engine bay, connecting the engine fan duct/air-intake housing to the heat-exchanger (or heater box) via the hose (typically on the right side).
• Cross-Reference / Alternative Numbers: 901 211 194 01 (current) supersedes and replaces 901 211 194 00.
• Material & Construction: Crafted from heat-resistant aluminium-lined hose, clad externally with the original brown-paper finish and sized to match the factory shape (60mm inner diameter, ~380mm length). Built for high-temperature engine-bay environment and correct airflow performance.
• Applications: Ideal when the original hose is cracked, delaminated, deformed, missing, or when restoring correct heating/airflow behaviour in the engine bay or passenger compartment on classic air-cooled Porsche cars.
This hot-air hose plays a vital role in engine and cabin heat management: if it's cracked, collapsed, or detached, you may experience reduced heater output, engine-bay overheating, erratic air-flow, or loss of original ducting performance. Installing a correctly specified replacement restores the original system’s performance and helps maintain correct engine and cabin temperature control.
When and why to replace:
• Visible cracking, splitting, or sagging in the old hose.
• Hose has been removed, reused too often or replaced with incorrect diameter/length.
• Heater output is weak or airflow to engine/compartment is abnormal.
• Restoring a classic 911/930 and you require original spec parts for authenticity and functionality.

What This Product Does
The connector joins vacuum pipework at the relevant connection point. Its role is to maintain the connection rather than generate vacuum or operate an actuator.
Functions
- Connects sections of vacuum pipework.
- Provides a replacement for a damaged or leaking connection.
- Supports continuity of the connected vacuum circuit.
Technical Details
- Brand: OE Match.
- 9P1129487 is identified as a distributing piece and moulded hose in the 911 Carrera diagrams.
- 911 Carrera L-Jetronic II applications: 930.20/21/26, 1984–86; 930.20/25/26, 1987–89. Air-injection diagrams also identify 930.26, including AUS, CH and S applications for 1984–86.
- 92857471705 is identified as a protective tube in the supplied 964 and 993 diagrams.
- 964 diagram applications: M64.01/02/03, 1989–94; 964 Turbo M30.69 and M64.50, 1991–94.
- 993 Carrera/4 diagram applications: M64.05/06/07/08, 1994–98. Diagram quantities vary by application and position; they do not establish the quantity supplied.
Symptoms of Fault
- Visible cracks or deterioration around the connection.
- Hissing near the vacuum pipe joint.
- Leakage identified during vacuum testing.
- Irregular operation of the connected vacuum-controlled component.
- Unstable idle where the leaking circuit affects the intake system.
Why Replacement Matters
A leaking connection can interrupt vacuum supply to the attached circuit. Renewing a confirmed faulty connector addresses that leak point; adjoining hoses and fittings should also be inspected for deterioration. OE Match develops replacement components around Porsche applications, using original references and application information to guide component selection.
FAQs
Does this replace a vacuum pump or actuator?
No. It is a pipework connector, not a pump, valve or actuator assembly.
Should nearby hoses be inspected?
Yes. Hardened or split hoses can leave the circuit leaking after the connector has been renewed.
Is the same connector used throughout every listed vehicle?
