Information
Vacuum hose
OE Match vacuum hose for Porsche 928 S4, GT, and GTS models from 1987 to 1995. This replacement hose fits from the left “Y” at the air guide elbow to the brake venturi / suction jet pump air guide, helping restore correct vacuum routing and intake system operation.
Fits:
Porsche 928 S4 / GT 1987 - 1991
* Engine code: 2841 / 2842 / 2847
Porsche 928 GTS 1992 - 1995
* Engine code: 2849 / 2850
Diagram ref no 10
The vacuum hose routes vacuum between the left “Y” connection at the air guide elbow and the brake venturi / suction jet pump air guide. Correct vacuum hose sealing helps maintain proper vacuum supply, supports brake assist operation, and prevents unmetered air or vacuum leaks that can affect engine running.
Functions
• Replaces the vacuum hose
• Fits from the left “Y” at the air guide elbow
• Connects to the brake venturi / suction jet pump air guide
• Supports correct vacuum routing
• Helps maintain brake vacuum assist system operation
• Helps prevent vacuum leaks and poor running
• Suitable for intake system service, vacuum leak repair, or engine bay restoration
• OE Match replacement for Porsche 928 S4, GT, and GTS vacuum system maintenance.
Why Replace This Part?
Vacuum hoses can harden, crack, split, collapse, or become loose due to age, heat, oil vapour exposure, and engine bay conditions. A damaged vacuum hose may cause vacuum leaks, rough idle, hesitation, poor throttle response, brake assist issues, intake air leaks, or incorrect vacuum system operation. Replacing the hose helps restore correct vacuum sealing and reliable system function.
When to Replace This Part
• Vacuum hose is cracked, brittle, split, collapsed, or leaking
• Rough idle, hesitation, or poor running is present
• Vacuum leak symptoms are detected
• Brake assist feels inconsistent or reduced
• Air guide elbow or suction jet pump area is being serviced
• Engine vacuum system maintenance is being carried out
• Vehicle is undergoing Porsche 928 engine bay restoration or refresh.
Where it fits on the car
This hose fits within the engine intake and vacuum system, running from the left “Y” at the air guide elbow to the brake venturi / suction jet pump air guide on Porsche 928 S4, GT, and GTS models.

Information
Breather hose, Crankcase to intake manifold.
This OE Match breather hose is a replacement crankcase ventilation hose used on Porsche 955 Cayenne S models. It connects the crankcase breather system to the intake manifold, helping route crankcase vapours back into the engine intake system.
Fits:
Porsche 955 Cayenne S 4.5L 2003 - 2006
Diagram ref no 5
The breather hose forms part of the engine crankcase ventilation system. It allows oil vapour and blow-by gases from the crankcase to be drawn into the intake manifold, where they can be burned through the combustion process. This helps reduce pressure inside the crankcase and supports cleaner, more efficient engine operation.
This hose fits in the engine bay, connecting the crankcase ventilation system to the intake manifold. It is part of the breather / PCV system and is positioned around the upper engine intake area, depending on engine layout.
Functions
• Connects the crankcase breather system to the intake manifold
• Helps route crankcase vapours back into the engine intake
• Supports correct crankcase pressure regulation
• Helps reduce oil vapour build-up inside the engine
• Assists emissions control by recirculating blow-by gases
• Helps maintain stable idle and smooth engine running
• OE Match replacement for cracked, brittle, or leaking original hoses
Why Replace This Part?
Breather hoses are exposed to heat, oil vapour, vacuum pressure, and age-related hardening. Over time, the hose can crack, split, collapse, soften, or leak, which may cause vacuum leaks, rough idle, poor running, oil mist around the engine, or crankcase ventilation faults. Replacing a worn breather hose helps restore correct ventilation and prevents unmetered air from entering the intake system.
When to replace:
• The hose is cracked, brittle, split, collapsed, or oil-soaked
• There is a vacuum leak or hissing noise near the intake manifold
• The engine has rough idle, hesitation, or poor running
• Oil vapour, residue, or mist is visible around the breather connection
• Crankcase ventilation or emissions-related faults are present
• The intake manifold or breather system is being serviced
• As preventative maintenance on ageing original breather pipework
