Audi Secondary Air Injection Hose Replacement

Audi Secondary Air Injection Hose

The secondary air injection hose carries fresh air from the pump to the exhaust stream. It plays a key role in reducing emissions during cold starts in your Audi. Over time, this hose can become brittle or cracked, leading to reduced air flow and a drop in emissions efficiency.

Why the Secondary Air Injection Hose Matters

This hose ensures the proper delivery of air to reduce unburned fuel emissions.

• Delivers Clean Air to Exhaust: Enables faster catalyst light-off for lower emissions.
• Prevents Vacuum Leaks: Maintains system pressure and airflow integrity.
• Protects Emissions System: Ensures all parts work as designed with correct air flow.
• Improves Startup Efficiency: Supports better fuel combustion when engine is cold.
