Hella 7.00216.06.0 Secondary Air Injection Pump

The Hella / Pierburg 7.00216.06.0 Secondary Air Injection Pump is an OEM-quality electric air pump designed to reduce cold-start emissions and support catalytic converter efficiency. Pierburg products are distributed by Hella, and this pump is engineered to meet or exceed original equipment specifications for a factory-correct fit and function.

The secondary air injection system works by pumping fresh air into the exhaust stream immediately after a cold start. This promotes post-combustion of unburned hydrocarbons and carbon monoxide in the exhaust, accelerating catalytic converter warm-up and reducing harmful emissions during the engine's warm-up phase. The system is controlled by the engine control unit and deactivates automatically once the lambda (oxygen sensor) control becomes active.

Key Features:

• OEM-equivalent replacement secondary air injection pump (also known as a smog pump or air injection reactor pump)
• Electric operation at 12V for consistent performance and quick response
• Engineered to OEM specifications for direct fit and reliable performance
• Helps reduce cold-start hydrocarbon and CO emissions
• Supports catalytic converter warm-up to minimize emissions during cold starts
• Premium-grade construction for long-lasting durability
• Manufactured by Pierburg, a Rheinmetall Automotive subsidiary and trusted OEM supplier

A failing secondary air injection pump can trigger diagnostic trouble codes such as P0410 and P0411, illuminate the check engine light, and result in increased exhaust emissions. Replacing the faulty pump with this Hella/Pierburg unit restores proper system function and emissions compliance.
