Hella 7.04389.08.0 Secondary Air Injection Pump

The Hella 7.04389.08.0 is a secondary air injection pump designed to reduce vehicle emissions during cold start and warm-up phases. This electric pump actively delivers fresh air into the exhaust system, enabling more complete combustion of unburned hydrocarbons and carbon monoxide before they reach the catalytic converter.

Key Features:

• Helps catalytic converter reach operating temperature faster
• Reduces harmful emissions during engine cold start
• Electrically operated for precise air delivery control
• Built to OE quality standards for reliable performance
• Designed for integration with vehicle emission control systems

Secondary air injection systems are critical for meeting modern emission standards by providing additional oxygen for post-combustion in the exhaust stream. The system typically operates for approximately 100 seconds during cold starts, significantly reducing HC and CO emissions while accelerating catalytic converter warm-up. Hella's engineering expertise ensures dependable operation in this demanding emissions control application.
