What This Product Does:
- Transfers vacuum to control the air injection valve or related components
- Supports proper operation of the secondary air injection system
- Helps reduce exhaust emissions during cold starts
- Assists in improving engine efficiency and emissions compliance
- Ensures accurate system response through proper vacuum delivery
Symptoms Of Wear Or Failure:
- Check engine light (emissions or secondary air injection fault codes)
- Rough idle or unstable engine RPM
- Hissing or whistling sound from the engine bay (vacuum leak)
- Reduced engine performance
- Poor fuel economy
- Failed emissions test
- Secondary air injection system not activating properly
- Cracked, brittle, or collapsed hose material
- Loose or disconnected vacuum line
Why Replacement Matters:
- Replacing a worn air injection vacuum line is important because it ensures proper vacuum delivery to the secondary air injection system. Over time, heat and engine bay exposure can cause the line to crack, harden, or leak.
- If a vacuum leak develops, the air injection system may not function correctly, leading to check engine lights, reduced emissions performance, rough idle, and potential failure of emissions testing.
- Installing a new vacuum line restores proper system control, prevents vacuum leaks, maintains engine efficiency, and ensures the vehicle meets emissions standards.

Function and Purpose
This hose is used across several critical systems.
It helps to:
• Supply air or pressure signals to the warm-up regulator (WUR)
• Support turbocharger wastegate operation and boost control
• Transport coolant to/from the expansion bottle (928)
• Maintain system pressure and fluid flow
• Ensure reliable engine and turbo performance
Why Replace Hoses
Hoses degrade over time due to heat, pressure, and fluid exposure.
Common issues include:
• Cracking or splitting
• Boost or vacuum leaks affecting performance
• Coolant leaks leading to overheating
• Hardening and reduced flexibility
Replacing worn hoses ensures safe operation and restores system efficiency.
