Hella 7.28247.13.0 Secondary Air Injection Pump

The Hella 7.28247.13.0 is a direct-fit secondary air injection pump (also known as a smog pump or SAI pump) engineered to OEM specifications. Designed to restore proper function to your vehicle's secondary air injection system, this pump helps reduce harmful cold-start emissions by forcing fresh air into the exhaust stream during the engine warm-up phase.

How It Works:

During cold starts, the engine runs rich and the catalytic converter has not yet reached operating temperature. The secondary air injection pump injects fresh air into the exhaust ports, promoting a secondary combustion reaction that converts harmful hydrocarbons (HC) and carbon monoxide (CO) into carbon dioxide (CO2) and water (H2O). This accelerates catalytic converter warm-up and significantly reduces cold-start emissions.

Key Features:

• OEM-quality construction from Hella, a trusted Tier 1 automotive supplier
• Direct replacement for failed or seized original secondary air pump
• Engineered to meet original equipment specifications for fit, form, and function
• Helps eliminate emission-related fault codes and MIL/check engine light caused by secondary air system failure
• Durable electric motor design with moisture-resistant construction
• Plug-and-play installation — no modification required

Common Failure Symptoms This Pump Addresses:

• Check engine light with secondary air injection system fault codes (P0410, P0411, P0412, etc.)
• Audible pump failure or no pump operation at cold start
• Failed emissions inspection due to secondary air system malfunction
• Moisture ingress causing pump seizure or electrical failure
