The breather hose routes crankcase vapours and ventilation flow through the intake system. A correctly fitted hose helps maintain proper air metering, reduce vacuum leaks, and prevent unmetered air from entering the intake tract.

Functions
• Replaces the breather hose from the air flow sensor boot “T” fitting
• Supports correct crankcase ventilation routing
• Helps maintain proper intake air metering
• Helps prevent vacuum leaks and unmetered air entry
• Supports smooth idle and reliable throttle response
• Suitable for intake system service, breather repair, or engine restoration
• OE Match replacement for Porsche 928 intake and breather system maintenance

Why Replace This Part?
Breather hoses can harden, crack, split, collapse, or become oil-soaked due to age, heat, oil vapour exposure, and engine bay conditions. A damaged hose may cause rough idle, poor running, vacuum leaks, intake air leaks, oil vapour smell, or incorrect air flow sensor readings. Replacing the hose helps restore correct breather system sealing and intake performance.

When to Replace This Part
• Breather hose is cracked, brittle, split, collapsed, or leaking
• Rough idle, hesitation, or poor running is present
• Vacuum leak symptoms are detected
• Oil vapour smell or residue is visible around the hose
• Air flow sensor boot or intake system service is being carried out
• Engine breather system maintenance is in progress
• Vehicle is undergoing Porsche 928 restoration or engine bay refresh

Where it fits on the car
This hose fits in the engine intake and breather system, running from the air flow sensor boot “T” fitting on Porsche 928 models.

This hose replaces the earlier Porsche part numbers 92811043201 and 92811043202.

What This Part Does / Functions
•  Routes crankcase breather vapours through the correct intake system path
•  Connects from the air flow sensor boot “T” fitting where specified
•  Helps maintain a sealed intake and breather system
•  Supports correct engine ventilation
•  Helps prevent unmetered air leaks in the intake system
•  Replaces a cracked, hardened, split or oil-softened original hose
•  Provides correct OE Porsche hose shape, fitment and connection size
•  Helps maintain smooth idle quality and correct engine running.

Why Replace This Part?
Breather hoses are exposed to heat, oil vapour, engine movement, age and intake vacuum. Over time, the rubber can harden, crack, collapse, split or become oil-contaminated. A damaged breather hose may allow air leaks, vapour leaks or poor crankcase ventilation, which can affect idle quality and engine performance. Replacing it with an OE Genuine Porsche breather hose helps restore the correct factory intake and ventilation layout on the Porsche 928.

Common Symptoms of a Faulty Breather Hose
•   Cracked, hardened or split rubber hose
•   Oil vapour smell from the engine bay
•   Poor idle quality
•   Intake air leak or vacuum leak
•   Engine hesitation or rough running
•   Loose or damaged connection at the “T” fitting
•   Collapsed or softened hose from age and oil vapour
•   Hose damage found during intake system service.

When to Replace This Part
•   If the original hose is cracked, brittle, split or leaking
•   During intake boot or air flow sensor boot replacement
•   When servicing the crankcase breather / ventilation system
•   If an intake air leak is traced to the breather hose
•   During engine bay restoration
•   When replacing aged rubber hoses on a Porsche 928
•   If the hose is oil-softened, loose or no longer sealing correctly
•   When restoring the intake system with OE Genuine Porsche parts.

Where It Fits on the Car
This breather hose fits in the engine intake / crankcase ventilation area of the Porsche 928. It is fitted from the air flow sensor boot “T” fitting and forms part of the engine breather hose routing.

Correct installation is important to ensure the intake system remains sealed and the breather system functions as intended.
