Hella 7.21852.24.0 Secondary Air Injection Pump

The Hella 7.21852.24.0 is a high-quality secondary air injection pump manufactured by Pierburg and distributed by Hella. This essential emissions control component is designed to inject fresh air into the exhaust stream, allowing unburned fuel to ignite more completely and reducing harmful hydrocarbon emissions.

Key Features:

• Direct replacement secondary air injection pump for European vehicles
• Manufactured to meet or exceed OEM specifications for reliable performance
• Helps vehicles pass emissions testing by reducing exhaust pollutants
• Durable construction engineered for long service life
• Quality-tested by ISO 9001 and Six Sigma certified manufacturer

How It Works:

The secondary air injection pump delivers clean air into the exhaust manifold during cold starts and specific operating conditions. This additional oxygen allows the catalytic converter to work more efficiently by promoting complete combustion of unburned hydrocarbons. The system helps reduce emissions, prevents rough idle conditions, and ensures optimal engine performance while meeting stringent environmental standards.

Signs of a Failing Air Pump:

• Check Engine light illumination with secondary air system codes
• Failed emissions testing
• Rough idle or engine stalling during cold starts
• Unusual noises from the pump area
• Reduced engine performance

Pierburg is a trusted name in automotive fuel and air management systems, with over a century of engineering expertise. When distributed by Hella, you can be confident in receiving a precision-manufactured component that restores your vehicle's emissions system to proper working order.
